Question

Given below are two statements :\ Statement I : Glycogen is similar to amylose in its structure.\ Statement II : Glycogen is found in yeast and fungi also.\ In the light of the above statements choose the correct answer from the options given below.

Professor PC Thomas Classes · Answer

(b) : Chemically, amylose is a long unbranched chain with 200-1000 α-D-(+)-glucose units held together by $\mathrm{C}_1-\mathrm{C}_4$ glycosidic linkage. Structure of glycogen is similar to amylopectin as it is a branched chain polymer of $\alpha-D$-glucose units in which chain is formed by $\mathrm{C}_1-\mathrm{C}_4$ glycosidic linkage whereas branching occurs by $\mathrm{C}_1-\mathrm{C}_6$ glycosidic linkage.
