Q
Why do Cellulose and Chitin have rigid Structures
A
Chitin: The GlcNAc residues in adjacent strands of chitin form hydrogen bonds with each other, resulting in linear fibrils of great strength.
Cellulose: The beta linkages of cellulose result in a rigid extended conformation in which each glucose residue is rotated 180 degrees relative to its neighbor. Extensive hydrogen bonding within and between the cellulose leads to formation of fibrils.
