Both starch and cellulose are glucose polymers. Why can animals easily degrade starch, but not cellulose?

Animals have enzymes to degrade a-1,4-glycosidic bonds, but not a-1,6-glycosidic bonds.

The glucose of cellulose has amino functional groups that participate in the formation of glycosidic bonds. Animals do not have the enzymes necessary to degrade these bonds.

Cellulose is much more rigid than starches because of the extensive hydrogen bonding between adjacent glucose polymers in cellulose. Animals are unable to destroy these hydrogen bonds.

Animals have the enzymes to degrade a-1,4-glycosidic bonds, but not b-1,4-glycosidic bonds..
