Question

Which of the following carbohydrates are branched polymers of glucose?

(i) Amylose

(ii) Amylopectin

(iii) Cellulose

(iv) Glycogen

Answer 1

(ii) Amylopectin

(iv) Glycogen

Explanation:

Amylopectin is insoluble in water and constitutes about 80- 85% of starch. It is a branched-chain polymer of α-D-glucose units in which chain is formed by C₁ – C₄ glycosidic linkage whereas branching occurs by C₁ – C₆ glycosidic linkage.

Glycogen: The carbohydrates are stored in animal body as glycogen. It is also known as animal starch because its structure is similar to amylopectin and is rather more highly branched.
