Why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

EXPLANATION:

Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body. But the polysaccharide like cellulose cannot be absorbed by our body. Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity. Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes. Thus, cellulose degradation requires a complex enzyme and cellulose.
