Cellulose Glycogen Molecule Made Straight Chain Glycosidic Describe

Cellulose, composed of β-glucose in straight chains with 1,4-glycosidic bonds, differs from glycogen, made of α-glucose in branched chains with 1,4- and 1,6-glycosidic bonds.

Differences between cellulose and glycogen: Cellulose is made of β-glucose, forming straight chains, while glycogen is made of α-glucose and is branched, sometimes coiled. Glycogen has 1,4- and 1,6- glycosidic bonds, while cellulose only has 1,4-.
