Question

Which among the following type of linkages is present in cellulose?

Options

• 1 → 6 β-glycosidic linkage

• 1 → 6 α-glycosidic linkage

• 1 → 6 α-glycosidic linkage

• 1 → 4 β-glycosidic linkage

Answer 1

1 → 4 β-glycosidic linkage

Explanation:

In cellulose, there is a 1 → 4 β-glycosidic bond. It is the most important component of plant cell walls. It's a straight-chain polysaccharide made up entirely of D glucose units linked together by a glycosidic bond between the C-1 of one glucose unit and the C-4 of the next.
