Due to the difference in structure, polysaccharides are assimilated differently by organisms. So, in many animals and humans, starch and glycogen are easily broken down and absorbed, but they don’t have an enzyme that breaks down cellulose, and only microorganisms can break down the bonds between glucose residues in cellulose. However, cellulose fibers contribute to intestinal motility, therefore, many animals and humans need normal digestion, carbohydrate functions.
