Question

Unbranched part of the glycogen molecule shows 1,6 linkage.

• A. True
• B. False

Answer 1

The correct option is B

False

Glycogen is a branched polymer consisting of linear chains of glucose residues with further chains branching off every 8 to 12 glucoses or so. Glucoses are linked together linearly by α(1→4) glycosidic bond from one glucose to the next. Branches are linked to the chains from which they are branching off by α(1→6) glycosidic bonds between the first glucose of the new branch and a glucose on the stem chain. Therefore its the branches that contain the α(1→6) glycosidic linkage.
