Cellulose and starch are both polymers of glucose units, but most animals can only use starch as a source of carbohydrate in their diets. Why are most animals incapable of digesting cellulose?
◦ Starch contains α linkages between carbons 1 and 4, where as cellulose contains β linkages between carbons 1 and 2.
◦ The glucose units of cellulose are in the open chain form and cannot be hydrolyzed by the cyclic-sugar specific enzymes of animals.
◦ The polymer of cellulose is simply too long to be completely digested by animals.
◦ Most animals do not produce enzymes which are capable of hydrolyzing β linkages between cellulose.
◦ This statement is incorrect. Most animals can digest cellulose.
