Cellulose, starch, and glycogen are all polymers of glucose. Which of the following are true? In cellulose and starch, glucoses are connected with beta-1,4 linkages, while glycogen uses alpha-1,4 linkages. Digestion of cellulose requires the cellulase enzyme. FALSE Cellulose is the least stable of the three. Humans can digest all polymers of glucose. All three contain alpha-1,6 glycosidic bonds. In cellulose, glucoses are arranged in straight chains, while glycogen and starch have a more helical structure.

Humans can digest starch but not cellulose because humans have enzymes that can hydrolyze the alpha (a) glycosidic linkages of starch but not the beta (B) glycosidic linkages of cellulose.

Three complex carbohydrates that are very important in living things are starch, cellulose, and glycogen (see below). All three of these polysaccharides are polymers of glucose, yet they behave very differently in our bodies. We can digest starch and glycogen, but not cellulose. Examine the drawing of these three polysaccharides below. What differences can you see between these molecules that might explain why? starch cellulose glycogen the glycogen molecule branches but cellulose does not the linking, covalent bond with oxygen is in the same position in all three molecules the hydroxyl groups (-OH) alternate their position within the molecule the functional group highlighted in pink alternates its position on the carbohydrate molecule
