Question

The difference between amylose and amylopectin is _________.

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

Answer 1

The correct option is B Amlyopetin have $1\to 4\alpha$-linkage and $1\to 6\alpha$- linkage

Amylose is a straight-chain polymer of D-glucose units.

The bonding involved is $1\to 4\alpha -$ linkage. Amylopectin is a branched chain polymer of D-glucose units.

The bonding involved is $1\to 4\alpha$ - linkage and $1\to 6\alpha$- linkage.

Hence, the correct answer is option B.
