C) They all contain peptide bonds.
D) They all form highly branched fibers.

Question

Quizplus · Accepted Answer

Cellulose, chitin, and peptidoglycan all form bonds between polymer chains that create parallel strands. Cellulose is composed of glucose in the beta form, while chitin is composed of N-acetylglucosamine in the beta form, and peptidoglycan is composed of N-acetylglucosamine and N-acetylmuramic acid linked by peptide bonds. However, they do not all contain peptide bonds and do not form highly branched fibers.
