Carbohydrates consist of fundamental building blocks (monomers) known as saccharides or sugars. In living organisms. the sugars known as monosaccharides, disaccharides, and polysaccharides are of most importance. One of the common monosaccharides which are of great importance to living things is glucose. Use the molecular model material to construct two molecules of glucose (Figure 4). CH,OH HO-C-H H-C-OH Construct two glucose molecules. If two monosaccharide molecules are combined by dehydration synthesis, the result is a disaccharide. If many are combined, a polysaccharide is formed. For example, starch is a polysaccharide type of carbohydrate composed of many glucose molecules combined together. H-C-OH ČH,OH Figure 4. Glucose CH,OH To construct a disaccharide molecule known as maltose, join your two glucose molecules together by bringing the hydroxyl group at the end of one molecule (reactive group #1) next to the hydroxyl group at the opposite end of the other glucose molecule (reactive group #2 of the other molecule). (See Figure 5 for which hydroxyl groups to use.) Remove a molecule of water and attach the two glucose molecules together. Reactive H Group #2 OH C OH H но Reactive H Group #1 OH Figure 5. Reactive groups of glucose.
