Question

Which of the following constitutes cellulose?

• A. Unbranched chain of glucose molecules linked by $\alpha -1,6$ glycosidic bonds
• B. Unbranched chain of glucose molecules linked by $\beta -1,4$ glycosidic bonds
• C. Branched chain of glucose molecules having $\alpha -1,6$ glycosidic bonds at the site of branching
• D. Branched chain of glucose molecules with $\alpha -1,6$ glycosidic bonds in the straight chain and $\beta -1,4$ linked bonds at the site 'of branching.

Answer 1

The correct option is B Unbranched chain of glucose molecules linked by $\beta -1,4$ glycosidic bonds

Cellulose is made up of a straight chain of glucose molecules linked by $\beta -1,4$ glycosidic bonds.
