Chemistry - Biomolecules Question with Solution | TestHub

Cellulose is a linear polysaccharide composed of D-glucose units connected by $\beta$–1,4-glycosidic bonds, which contribute to its linear structure, robust hydrogen bonding, and resultant rigidity and insolubility.
Unlike cellulose, starch (amylose) features $\alpha$–1,4-glycosidic bonds, while amylopectin and glycogen incorporate $\alpha$–1,6-glycosidic linkages at branch points.
The correct identification is option B.
