Carbohydrates are called saccharides or, if they are relatively small, sugars. Carbonyl Functional Group; Carbohydrates. A monomer is the smallest unit of a polymer. What is the difference between a monomer and a monosaccharide? Affiliate Disclosure: Please note that each post may contain affiliate and/or Carbohydrates are organic compounds. Group of molecules that make up a group of atoms. Figure 4. The two saccharides are linked through an oxygen atom. Monosaccharides Monosaccharides are simple sugars. Amylose and amylopectin are two different forms of starch. Carbohydrates can contain hydroxyl (alcohol) groups, ethers, aldehydes and/or ketones. As shown in the figure above, every other glucose monomer in cellulose is flipped over, and the monomers are packed tightly as extended, long chains. These chains cluster together to form parallel bundles that are held together by hydrogen bonds between hydroxyl groups. They cannot be hydrolyzed into a simpler form. Interrelations between structural parameters and functional groups, the molecular weight ranges, and the different lignin sources are discussed. Functional Groups of Lipids 1. The Chemistry of Carbohydrates - ThoughtCo They are subdivided into two classes aldoses and ketoses on the basis of whether they are aldehydes or ketones. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Carbohydrates are made of single sugars, or monosaccharides and contain the functional groups, hydroxyl groups and esters. Glucose, galactose, and fructose are all hexoses. Given below is a brief account of the structure and functions of carbohydrate groups. The answer to that is that it depends on the final structure of the carbohydrate. All carbohydrates contain alcohol functional groups, and either an aldehyde or a ketone group (or a functional group that can be converted to an . Lactose is a disaccharide consisting of the monomers glucose and galactose. Learn more information about functional groups of carbohydrates.
