Question

Cellulose, the most important constituent of the plant cell wall, is made up of

• A. Unbranched chain of glucose molecules linked by α, 1, 4 glycosidic bond
• B. Unbranched chain of glucose molecules linked by β, 1, 4 glycosidic bond
• C. Branched chain of glucose molecules linked by α, 1, 6 glycosidic bond at the site of branching
• D. Branched chain of glucose molecules linked by β, 1, 4 glycosidic bond in straight chain and α, 1, 6 glycosidic bond at the site of branching

Answer 1

The correct option is B

Unbranched chain of glucose molecules linked by β, 1, 4 glycosidic bond

Cellulose is made up of glucose monomers. It is an unbranched chain of glucose molecules linked by a β,1,4 glycosidic bond.
