Question

The difference between amylose and amylopectin is

• A. Amylopectin have $1\to 4\alpha$ -linkage and $1\to 6\beta$ -linkage
• B. Amylose have $1\to 4\alpha$ -linkage and $1\to 6\beta$ -linkage
• C. Amylopectin have $1\to 4\alpha$ -linkage and $1\to 6\alpha$ -linkage
• D. Amylose is made up of glucose and galactose

Answer 1

Answer: (C)

Amylose and amylopectin are polymers of $\alpha$ - D- glucose, so $\beta$ -link is not possible. Amylose is linear with $1\to 4\alpha$ -linkage whereas Amylopectin is branched and has both $1\to 4$ (for linear chain) and $1\to 6\alpha$ -linkages (for branching).
