Amino groups are polar so they are also hydrophilic. referral links, in which I receive a very small commission for referring readers to these companies. General names for carbohydrates include sugars, starches, saccharides, and polysaccharides. As the backbone of the large molecules of living things, hydrocarbons may exist as linear carbon chains, carbon rings, or combinations of both. Without functional groups, everything would be straight chain alkanes and other boring hydrocarbons. Answer link Aldoses have a carbonyl group (indicated in green) at the end of the carbon chain and ketoses have a carbonyl group in the middle of the carbon chain. No. Group of molecules that make up a group of atoms. When the ring forms, the side chain it closes on is locked into an or position. If CH2OH is on the same side of OH then beta otherwise alfa. In contrast to unsaturated fats, triglycerides without double bonds between carbon atoms are called saturated fats, meaning that they contain all the hydrogen atoms available. Carbon binds to oxygen, hydrogen, and nitrogen covalently to form the many molecules important for cellular function. B) Each carbon can form three covalent bonds that can be polar or non-polar. Figure 6. Because of the way the subunits are joined, the glucose chains have a helical structure. There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides. Cellulose is the most abundant natural biopolymer. In the trans configuration, the carbons form a more or less linear structure, whereas the carbons in the cis configuration make a bend (change in direction) of the carbon backbone. Some of the important functional groups in biological molecules are shown above: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl (not shown). So it's important to learn functional groups, and how they will interact with nucleophiles and electrophiles to react to form new organic molecules. Carbohydrates are biological molecules made of carbon, hydrogen, and oxygen in a ratio of roughly one carbon atom ( \text C C) to one water molecule ( \text H_2\text O H2O ). Draw simple organic molecules that contain the following functional groups. Figure 3. For instance, in solution, glucoses main configuration is a six-membered ring. So they are sugars with either aldehyde (aldo-sugar)or ketone ( keto-sugar) functional groups attached with them. These additional atoms allow for functionality not typically seen in hydrocarbons. In their simplest form, carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Since carbohydrates contain a carbonyl and an alcohol functional groups, they can form intramolecular (cyclic) hemiacetals. The structure for one of the most common saccharides, glucose, is shown here. a long chain molecule with identical group of atoms. answer choices. Methane, an excellent fuel, is the simplest hydrocarbon molecule, with a central carbon atom bonded to four different hydrogen atoms, as illustrated in Figure \(\PageIndex{1}\). Although energy storage is one important role for polysaccharides, they are also crucial for another purpose: providing structure. All of those H-bonds also make them quite "sticky". Classification according to Functional group Aldose sugars having an aldehyde functional group R-HC=O Ketose sugars having a ketone functional group R 2 -C=O Fructose is a structural isomer of glucose and galactose (has the same atoms, but bonded together in a different order). . Glucose & Galactose Which Monosaccharides is a ketone? II. Some of that carbohydrate is in the form of sugars. Even the elevated glucose level (hyperglycemia) seen in uncontrolled diabetes cause changes in osmotic pressure that are responsible for some of the symptoms, such as increased urination and excessive thirst. Common disaccharides include lactose, maltose, and sucrose (Figure 5). Step 1/4. Five- and six-carbon monosaccharides exist in equilibrium between linear and ring form. By number of carbons: glyceraldehyde (triose), ribose (pentose), and glucose (hexose). In some cases, its important to know which carbons on the two sugar rings are connected by a glycosidic bond. The cell wall of plants is mostly made of cellulose, which provides structural support to the cell. Disaccharides ("di-" = two) form when two monosaccharides undergo a dehydration reaction (also known as a condensation reaction or dehydration synthesis). Carbohydrates can contain hydroxyl (alcohol) groups, ethers, aldehydes and/or ketones. Carbohydrates whose oxidized functional group is aldehyde group. Direct link to Laurent's post Well from what I learned , Posted 5 years ago. Stereochemistry of the compound. The brain is also highly sensitive to low blood-glucose levels because it uses only . What does R' stands for? Unfortunately there isn't a universally accepted definition for what makes up a carbohydrate. Why are galactose and glucose isomers, when the hydroxyl group that is "flipped" is linked to the chain by single bonds only? A: First calculate the number of moles for ammonia and then use mol to mol ratio to calculate the mass. Majority of the monosaccharides found in the human body are of which type . To log in and use all the features of Khan Academy, please enable JavaScript in your browser. Carboxyl 3. Here, because the #C=O# bond is bridged by two carbons instead of one carbon and one hydrogen, it is a ketone functional group. Cellulose is specific to plants, but polysaccharides also play an important structural role in non-plant species. Structure of ketone: carbonyl bonded to R and R' groups (carbon-containing groups) on both sides. They also come in a variety of forms. Clearly illustrated here the carbonyl group bonds with a carbon atom to form a ring structure that is often found in polysaccharides that usually form hydrogen bonds with the hydroxyl groups. In order to see which functional groups are present in carbohydrates, we must look at the functional groups present in the more basic building blocks. The former sugars are called aldoses based on the aldehyde group that is formed; the latter is designated as a ketose based on the ketone group. Whenever blood glucose levels decrease, glycogen is broken down to release glucose in a process known as glycogenolysis. In a polymer, because there are so many H-bonds, this can provide a lot of strength to the molecule or molecular complex, especially if the polymers interact. Whenever blood glucose levels decrease, glycogen is broken down via hydrolysis to release glucose monomers that cells can absorb and use. Structure of aldehyde: carbonyl bonded to a H on one side and to an R group (carbon-containing group) on the other. Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. They cannot be hydrolyzed into a simpler form. Similarly, the D-form of glucose is the main product of photosynthesis and the L-form of the molecule is rarely seen in nature. Group of atoms that give specific characteristics to a molecule. Functional groups are groups of atoms that confer specific properties to hydrocarbon (or substituted hydrocarbon) chains or rings that define their overall chemical characteristics and function. By carbonyl position: glyceraldehyde (aldose), dihydroxyacetone (ketose). What functional groups are found in proteins? A carbohydrate must be at least a tetrose to do that, so intramolecular cyclic forms don't exist for smaller carbohydrates. They are found along the carbon backbone of macromolecules. Here are a few quick and simple rules: For a short video on carbohydrate classification, see the 10-minute Khan Academy video by clicking here. This set of Organic Chemistry Multiple Choice Questions & Answers (MCQs) focuses on "Carbohydrates". During this process, the hydroxyl group of one monosaccharide combines with the hydrogen of another monosaccharide, releasing a molecule of water and forming a covalent bond. Carbohydrates That Will Help You Lose Weight What Do You Need To Know About Carbohydrates? Configurational and conformational isomerism play an important role. Maltose, or malt/grain sugar, is a disaccharide formed by a dehydration reaction between two glucose molecules. We often use hydrocarbons in our daily lives as fuelslike the propane in a gas grill or the butane in a lighter. Simple carbohydrates can be classified based on the functional group found in the molecule, i.e ketose (contains a ketone) or aldose (contains an aldehyde). 22407 views A long chain of monosaccharides linked by glycosidic bonds is known as a polysaccharide ("poly-" = many). Glucose, galactose, and fructose are all hexoses. The name "carbohydrate" means a "hydrate of carbon." The name derives from the general formula of carbohydrate is C x (H 2 O) y - x and y may or may not be . Introduction: Christian Orthodox fasting is a pattern high in complex carbohydrates and low in refined carbohydrates. A charged group is either positive or negative (gains or loses an electron) and a polar group contains atoms that have a difference in electronegativity. Cellulose fibers and molecular structure of cellulose. Browse functional groups biology resources on Teachers Pay Teachers, a marketplace trusted by millions of teachers for original educational resources. The short molecules are soluble in polar substances like water because they are relatively polar. It may also include their derivatives which produce such compounds on hydrolysis. They are as follows: 1. In order to see which functional groups are present in carbohydrates, we must look at the functional groups present in the more basic building blocks. The element _______is found in all of the organic compounds. Functional groups are groups of atoms that are found along the carbon backbone (composed of carbon and hydrogen atoms) of organic molecules and they impart specific chemical . -has carbonyl group (O=C) in the middle link to other carbon atoms. Direct link to Olivia's post Are aldehydes and ketones, Posted 7 years ago. Notice that here both glucose and fructose are drawn in their cyclic ring form. In sucrose, a glycosidic linkage is formed between the C1 carbon in glucose and the C2 carbon in fructose. Carbohydrates are simple sugar derivatives like glucose, fructose, and galactose that are linked together (or polymerized). (The reaction also releases a water molecule, not pictured.). Affiliate Disclosure: Please note that each post may contain affiliate and/or Most large biological molecules in fact contain many types of atoms beyond just carbon and hydrogen. Direct link to Ivana - Science trainee's post If something has '-yl' su, Posted 5 years ago. Whatever the answer, this is not to be confused with the reason cellulose is so strong (which is due to the hydrogen bonds acting between different polymers of glucose, forming thin fibrils), am I correct? Specifically, carbohydrates are known for their functionality as units of energy, which is why "carbs" are an essential part of the human diet. If the hydroxyl is up (on the same side as the CH. While we may be most familiar with the role carbohydrates play in nutrition, they also have a variety of other essential functions in humans, animals, plants, and bacteria. Saccharides - and by extension carbohydrates - are composed of only three atoms: carbon, hydrogen and oxygen. Q: Urea (HNCONH) is used extensively as a nitrogen source in fertilizers. In the table, what is the difference between a functional group being polar and being charged? Functional groups are usually classified as hydrophobic or hydrophilic depending on their charge or polarity characteristics. Overview of carbohydrates, including structure and properties of monosaccharides, disaccharides, and polysaccharides. Thats great for plants, but what about us? These groups play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Fructose and ribose also form rings, although they form five-membered rings as opposed to the six-membered ring of glucose. Sterols and Steroid Glycosides Functional Groups of Lipids Functional groups of lipids are groups of lipid molecules that perform specific biological functions. { "1.01:_Biological_Foundations" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.02:__Atoms_Ions_Molecules" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.03:_Intermolecular_Forces" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.04:_Carbon_and_Functional_Groups" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "1.05:_Water_Equilibrium_and_Buffers" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, { "00:_Front_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "01:_Chemical_and_Biological_Foundations" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "02:_Structure_and_Function-_Proteins" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "03:_Catalysis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "04:_Structure_and_Function-_Nucleic_Acids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "05:_Structure_and_Function-_Carbohydrates_and_Lipids" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "06:_Energy_and_Metabolism" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "07:_Regulation_of_Metabolism_and_Homeostasis" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "08:_Biotechnology_and_Other_Applications_of_Biochemistry" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "09:_Basic_Techniques" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "10:_Supplemental_Modules_(Biochemistry)" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()", "zz:_Back_Matter" : "property get [Map MindTouch.Deki.Logic.ExtensionProcessorQueryProvider+<>c__DisplayClass228_0.b__1]()" }, [ "article:topic", "enantiomers", "structural isomers", "isomers", "functional group", "hydrocarbon", "aromatic hydrocarbon", "aliphatic hydrocarbon", "authorname:openstax", "showtoc:no", "license:ccby", "transcluded:yes", "geometric isomer", "organic molecule", "substituted hydrocarbon", "source[1]-bio-1786" ], https://chem.libretexts.org/@app/auth/3/login?returnto=https%3A%2F%2Fchem.libretexts.org%2FCourses%2FCalifornia_Polytechnic_State_University_San_Luis_Obispo%2FSurvey_of_Biochemistry_and_Biotechnology%2F01%253A_Chemical_and_Biological_Foundations%2F1.04%253A_Carbon_and_Functional_Groups, \( \newcommand{\vecs}[1]{\overset { \scriptstyle \rightharpoonup} {\mathbf{#1}}}\) \( \newcommand{\vecd}[1]{\overset{-\!-\!\rightharpoonup}{\vphantom{a}\smash{#1}}} \)\(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\) \(\newcommand{\id}{\mathrm{id}}\) \( \newcommand{\Span}{\mathrm{span}}\) \( \newcommand{\kernel}{\mathrm{null}\,}\) \( \newcommand{\range}{\mathrm{range}\,}\) \( \newcommand{\RealPart}{\mathrm{Re}}\) \( \newcommand{\ImaginaryPart}{\mathrm{Im}}\) \( \newcommand{\Argument}{\mathrm{Arg}}\) \( \newcommand{\norm}[1]{\| #1 \|}\) \( \newcommand{\inner}[2]{\langle #1, #2 \rangle}\) \( \newcommand{\Span}{\mathrm{span}}\)\(\newcommand{\AA}{\unicode[.8,0]{x212B}}\), status page at https://status.libretexts.org, Describe the role of functional groups in biological molecules. Therefore, carbon atoms can form up to four covalent bonds with other atoms to satisfy the octet rule. There are many more functional groups,any tips for remembering there names? The equilibrium between the carbonyl forms of aldehydes or ketones and their associated acetal/hemiacetal (or ketal/hemiketal) forms also plays a critical role during the body's metabolism of xenobiotics (drugs). Direct link to Ivana - Science trainee's post Because it requires break, Posted 7 years ago. Well from what I learned beta-glycosidic linkages are stronger due to the way bonds criss-cross between every alternate glucose molecule such as cellulose making it both physically and chemically stable. Fructose The 3 Carboxyl Groups 1. Several classifications of carbohydrates have proven useful, and are outlined in the following table. Two industrial black liquors and three precipitated lignins were fractionated, and their functional groups were determined, providing molar mass-dependent profiles. Lipids---carboxylic acid with long hydrocarbon chains (usually above 16 C long). The sucrose has a hydroxyl group, acetal group, and glycosidic linkage. Monosaccharides are classified based on the position of their carbonyl group and the number of carbons in the backbone. Molecules with other elements in their carbon backbone are substituted hydrocarbons. A) Carbon is electropositive. If the latter is true, why is deoxyribose a carbohydrate with a formula C5H10O4? Solve any question of Biomolecules with:- Patterns of problems > Was this answer helpful? Does this happen or is there a reason why it can't? a long chain of different atoms. Its four major element constituents are carbon, hydrogen, oxygen, and nitrogen. Among the hydrophilic functional groups is the carboxyl group found in amino acids, some amino acid side chains, and the fatty acids that form triglycerides and phospholipids. Saturated fats are a solid at room temperature and usually of animal origin. Accessibility StatementFor more information contact us atinfo@libretexts.orgor check out our status page at https://status.libretexts.org. Top: amylose has a linear structure and is made of glucose monomers connected by 1-4 glycosidic linkages. What should I start learning after learning the basics of alkanes, alkenes, and alkynes? To add to the excellent reply from Okapi, another reason why glucose is stored as glycogen is that if it were stored as free glucose, this would cause osmotic pressure to increase such that cell membranes would rupture. Often, these additional atoms appear in the context of functional groups. The carbonyl group bonds with a carbon atom to form a ring structure that is often found in polysaccharides that usually form hydrogen bonds with the hydroxyl groups. Direct link to prakash's post There are many more funct, Posted 7 years ago. Functional groups in a coordination complex which bind to a central atom are called ligands. Clearly illustrated here the carbonyl group bonds with a carbon atom to form a ring structure that is often found in polysaccharides that usually form hydrogen bonds with the hydroxyl groups. (a) Identify the functional groups in aspartame, the artificial sweetener in Equal. On the other hand, triglycerides with trans double bonds (popularly called trans fats), have relatively linear fatty acids that are able to pack tightly together at room temperature and form solid fats. Fischer projection; Straight chain. Sponsored by Beverly Hills MD Generally, carbohydrates are classified into three major groups. In the human diet, trans fats are linked to an increased risk of cardiovascular disease, so many food manufacturers have reduced or eliminated their use in recent years. Because carbohydrates have many hydroxyl groups associated with the molecule, they are therefore excellent H-bond donors and acceptors. Thus, propane, propene, and propyne follow the same pattern with three carbon molecules, butane, butane, and butyne for four carbon molecules, and so on. For instance, the diagram below shows glucose and fructose monomers combining via a dehydration reaction to form sucrose, a disaccharide we know as table sugar. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Because it requires breaking off the bonds. Carbohydrate---alcohol and (aldehyde or ketone). Many cells prefer glucose as a source of energy versus other compounds like fatty acids. In aqueous solutions, monosaccharides are usually found in ring form (Figure 3). Trioses, pentoses, and hexoses have three, five, and six carbons in their backbones, respectively. The present review aims to comprehensively explore the existing available clinical data concerning the potential favorable impact of the dietary pattern of Christian Orthodox fasting on human health . Monosaccharides. Cellulases can break down cellulose into glucose monomers that can be used as an energy source by the animal. Carbohydrates are a group of naturally occurring carbonyl compounds (aldehydes or ketones) that also contain several hydroxyl groups. The question: Is there a method to the naming of these that might help me remember? Some D forms of amino acids are seen in the cell walls of bacteria, but never in their proteins. For example, many carbohydrates contain functional groups (remember them from our basic discussion about chemistry) besides the obvious hydroxyl. Direct link to Gen L's post Why are galactose and glu, Posted 6 years ago. In the 5th paragraph, there is discussion about carboxyl groups and carboxylate and, although these have been discussed in previous videos, I noticed that I did not remember which was which. Here we can identify multiple hydroxyl (alcohol) functional groups and one aldehyde functional group. Indeed, they play an important role in energy storage, in the form of polysaccharides . No, single bonds stereoisomers such as some enatiomers are not interchangeably because they are stuck in the three dimension world, Looking at my notes from the "Properties of Carbon" module, I would say that. Those are the functional groups consisting of only carbons and hydrogens. Simple carbohydrates can be classified based on the number of carbon atoms in the molecule, as with triose (three carbons), pentose (five carbons), or hexose (six carbons). Learn more information about functional groups of carbohydrates. If not, why not? Functional groups are the basis of why molecules can and will react with each other. 1. Figure 5. When you eat French fries, potato chips, or a baked potato with all the fixings, enzymes in your digestive tract get to work on the long glucose chains, breaking them down into smaller sugars that your cells can use. Simple carbohydrates can be classified based on the functional group found in the molecule, i.e ketose (contains a ketone) or aldose (contains an aldehyde). If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Carbon and hydrogen can form hydrocarbon chains or rings. Direct link to Lim Pin Seng's post No, single bonds stereois, Posted 3 years ago. Short Answer. I thought only double+triple bonds forced atoms to stay where they are. The functional groups in a macromolecule are usually attached to the carbon backbone at one or several different places along its chain and/or ring structure. For instance, R might be an ethyl (CH, Posted 6 years ago. In this article we'll discuss functional groups of carbohydrates. They include: hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl. The answer to that is that it depends on the final structure of the carbohydrate. The most common disaccharide is sucrose (table sugar), which is made of glucose and fructose. What functional groups are found in carbohydrates? As illustrated in Figure 6, amylose is starch formed by unbranched chains of glucose monomers (only 1-4 linkages), whereas amylopectin is a branched polysaccharide (1-6 linkages at the branch points). Common disaccharides: maltose, lactose, and sucrose, A long chain of monosaccharides linked by glycosidic bonds is known as a, In starch, the glucose monomers are in the form (with the hydroxyl group of carbon. Fats with at least one double bond between carbon atoms are unsaturated fats. However, sugars will only have one aldehyde OR one ketone functional group. This note covers the following topics:Derivatives Of Hydrocarbons, Alcohols, Phenols, Ethers And Epoxides , Derivatives Of Hydrocarbons, Aldehydes, Ketons, Carboxylic Acids, Functional Derivatives Of Monocarboxylic Acids , Nitro Compounds, Organosulphur And Organo Phosphorus, Organic Compounds Of Nitrogen, Amino Compounds , Organosulphur And . These forms exist in equilibrium with each other, but equilibrium strongly favors the ring forms (particularly in aqueous, or water-based, solution). Monosaccharides ("mono-" = one; "sacchar-" = sweet) are simple sugars; the most common is glucose. Are all molecules with a carbonyl group (C=O) and hydroxyl group (OH) carbohydrates? Lastly, we must consider functional groups that arise through the linking of saccharides. This page titled 1.4: Carbon and Functional Groups is shared under a CC BY license and was authored, remixed, and/or curated by OpenStax. Functional groups in biological molecules play an important role in the formation of molecules like DNA, proteins, carbohydrates, and lipids. Examples of biological molecules that incorporate the benzene ring include some amino acids and cholesterol and its derivatives, including the hormones estrogen and testosterone. . These groups play an important role in forming molecules like DNA, proteins, carbohydrates, and lipids. 1. Carbohydrates usually contain a carbonyl ( = O) and hydroxyl ( OH) functional group. 3. Carbohydrates can be classified based on how many sugars they contain: Answer 1) Carbohydrates are one of the three macronutrients (along with proteins and fats) that are essential for the human body. Direct link to Citrus's post A charged group is either, Posted 5 years ago. According to the previous lesson about ethene/ethane, galactose and glucose should be the same thing because the flip happens around single bonds. Furthermore, the overall geometry of the molecule is altered by the different geometries of single, double, and triple covalent bonds, illustrated in Figure \(\PageIndex{2}\). Direct link to John Morgenthaler's post In the 5th paragraph, the, Posted 4 years ago. Artificial sweeteners have gained in popularity as consumers seek out products without sugar, but a new study suggests a potential link between keto-friendly sweetener erythritol and an elevated . However, even with these types of substitutions, the basic overall structure of the carbohydrate is retained and easily identified. Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides. Are the groups that don't specify if they are charged or uncharged just neither? They (mono- = "one"; sacchar- = "sweet") are simple sugars, the most common of which is glucose. Direct link to Oyuna Nataa's post Is all groups hydrophilic, Posted 5 years ago. Direct link to David Son's post how alkanes are less reac, Posted 7 years ago. Each of its four hydrogen atoms forms a single covalent bond with the carbon atom by sharing a pair of electrons. They are not mirror images of each other (which is what an enantiomer is).
