Amylopectin is a _____ chain.

Amylopectin is a _____ chain.

• A. linear
• B. branched
• C. coiled
• D. circular

Answer: (B)

Amylopectin is a highly branched polymer of glucose. It’s built mainly from chains of glucose linked by α-1,4 bonds, with frequent α-1,6 linkages creating branch points throughout the molecule. This branching gives amylopectin a branched structure, distinguishing it from a purely linear polymer like amylose. The idea of it being coiled describes how linear glucose chains can fold, but the defining feature here is the many branches. A circular description would imply a closed loop, which isn’t how these polysaccharides are arranged.
