What is monomer used in cellulose, a straight chain polysaccharide?
Options
- A-D-glucose
- B-D-fructose
- C-D-glucose
- 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
