Starch and glycogen consist of α-glucose units linked by α-1,4 and α-1,6 glycosidic bonds (glycogen is more branched), while cellulose is made of β-glucose units linked by β-1,4 bonds.
Starch and Glycogen are composed of α units with α-1,4 and α-1,6 linkages (glycogen has more branching). Cellulose is composed of β units with β-1,4 linkages.
| Front | Starch, Glycogen and Cellulose .are composed of which units α or β .which linkages are present in each |
|---|---|
| Back | Starch α units only α-1,4 (amylose) 1,4 + 1,6 (amylopectin) Glycogen α units only α-1,4 + 1,6 Cellulose β units only (upright and inverted) β-1,4 only |
