Chemistry - Biomolecules Question with Solution | TestHub

Cellulose is a straight-chain polysaccharide composed entirely of $\beta$-D-glucose units.

These glucose units are joined together by glycosidic bonds between the C-1 of one glucose unit and the C-4 of the next glucose unit.

Since the glucose units are in the $\beta$-anomeric form, the linkage is a $\beta -1,4$-glycosidic linkage.

Answer: $\beta -1,4$
