Question

Cellulose is made up of _______________________.

• A. Unbranched chain of glucose molecules linked by $\beta 1-4$ glycosidic bonds
• B. Branched chains of glucose molecules linked by $\alpha 1-6$ glycosidic bond in straight chains and $\alpha 1-6$ glycosidic bonds at branch points
• C. Unbranched chains of glucose molecules linked by $\alpha 1-6$ glycosidic bonds
• D. Branched cgains of glucose molecules linked by $\alpha 1-6$ glycosidic bonds at branch points

Answer 1

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

Cellulose is a polysaccharide that is formed by the linkage of beta 1,4 linkage of the glucose unit. It is an important component of the cell wall in plants. It does not have a free aldehyde group so it is non reducing sugar. It is a free polysaccharide as it exists in form of a long chain-like structure and mainly found in plants.

So, the correct option is (A).
