What is monomer used in cellulose, a straight chain polysaccharide?
- A$\alpha$-D-glucose
- B$\alpha$-D-fructose
- Correct answerC$\beta$-D-glucose
- D$\beta$-D-fructose
Solution
Cellulose is a straight-chain polysaccharide composed exclusively of $\beta$-D-glucose units.
These monomer units are joined together by $\beta$-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 $\beta$-D-glucose.
Answer: $\beta$-D-glucose
These monomer units are joined together by $\beta$-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 $\beta$-D-glucose.
Answer: $\beta$-D-glucose
Hence, the correct answer is option: 'C'.
