Question

The difference between amylose and amylopectin is

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

Answer 1

Answer: (B)

Amylose is a straight-chain polymer of D-glucose units.
The bonding involved is $1 \rightarrow 4 \alpha$ - linkage. Amylopectin is a branched chain polymer of D-glucose units.
The bonding involved is $1 \rightarrow 4 \alpha$ - linkage and $1 \rightarrow 6 \alpha$ - linkage.
