Question

Amylopectin is composed of

• A. $\alpha $ -D-glucose with $C_{1}—C_{4}$ and $C_{1}—C_{6}$ linkage
• B. $\alpha $ -D-glucose with $C_{1}—C_{4}$ and $C_{2}—C_{6}$ linkage
• C. $\beta $ -D-glucose with $C_{1}—C_{4}$ and $C_{2}—C_{6}$ linkage
• D. $\beta $ -D-glucose with $C_{1}—C_{4}$ and $C_{1}—C_{6}$ linkage

Answer 1

Answer: (A)

Amylopectin is a homopolymer of $\alpha $ D-glucose having $C_{1}—C_{4}$ $\beta $ -glycocidic linkage (for linear chain formation) and $C_{1}—C_{6}$ linkage (for branch chain formation).
