Question

D - Glucose units in cellulose are joint by

• A. $\alpha$ - 1, 4 glycosidic bond
• B. $\beta$ - 1, 6 glycosidic bond
• C. $\beta$ - 1, 4 glycosidic bond
• D. Peptide bond

Answer 1

Answer: (C)

D-glucose units in cellulose are joint by $\beta -1$. 4 glycosidic bond. Cellulose is a straight chain polysaccharide composed only of $\beta$ -D glucose units that are linked together by glycosidic linkage between C-l of one glucose unit and C- 4 of the next glucose unit.
