Question

Amylopectin is

• A. Water soluble
• B. Water insoluble
• C. $C_1-C_4$ glycosidic bonds and $C_1-C_6$ glycosidic bonds.
• D. (b) and (c) above.

Answer 1

The correct option is D (b) and (c) above.

Amylopectin is the water insoluble branched constituent of starch which makes up 80-85% of its structure. It consists of straight chains of glucose through $C_1-C_4$ linkage, with the $C_1$ of the terminal glucose of each chain linking with the $C_6$ of another glucose unit in the next chain.

Hence option (d) is correct.
