Question

Which statement in the following is correct?

• A. Cellulose are linear polymers of $\beta -$ glucose molecules with $\beta -1,4-$ linkages
• B. Starches are polymers of $\alpha -$ glucose molecules with $\beta -1,4-$ linkages and some $\beta -1,6-$ cross-linkages
• C. Proteins are polyamides of $\beta -$ amino acids
• D. The structural information about carbohydrate biosynthesis is contained in a class of compounds called nucleic acids, e.g. $RNA$ and $DNA$

Answer 1

Answer: (A)

Cellulose is polymers of $\beta -$ glucose with $\beta -1,4-$ linkages while Starches are polymers of $\alpha -$ glucose molecules with $\alpha -1,4-$ linkages and $\alpha -1,6-$ cross-linkages. Proteins are polymers of $\alpha -$ amino acids
