Question:

Glycogen is a branched chain polymer of α-D-glucose units in which chain is formed by C1-C4 glycosidic linkage whereas branching occurs by the formation of C1-C6 glycosidic linkage. Structure of glycogen is similar to: amylose, amylopectin, cellulose, glucose

glucose

cellulose

amylose

amylopectin

Solution:

Amylopectin is a branched chain polymer of α-D glucose units. Here, the linear chains are formed by C1—C4 glycosidic linkage whereas branching occurs by the formation of C1-C6 glycosidic linkage. Thus, structure of glycogen is similar to amylopectin.
