What is monomer used in cellulose, a straight chain polysaccharide?

Options

  1. A-D-glucose
  2. B-D-fructose
  3. C-D-glucose
  4. D-D-fructose

Correct answer

C. -D-glucose

Step-by-step solution

Cellulose is a straight-chain polysaccharide composed exclusively of -D-glucose units. These monomer units are joined together by -1,4-glycosidic linkages between the C1 of one glucose unit and the C4 of the adjacent glucose unit. Thus, the monomer used in cellulose is -D-glucose. Answer: -D-glucose
