Question
What is glycogen? How is it different from starch?
✓
Answer
Glycogen is a condensation polymer of $\alpha$ - D glucose. Starch is not a single compound but is a mixture of two components-a water soluble component called amyldse (15 - 20%) and water insoluble component amylopectin (80 - 85%). Amylose is a linear polymer of $\alpha$ - D - glucose. But both glycogen and amylopectin are branched polymers of $\alpha$ - D - glucose; father glycogen is more highly branched than amylopectin as amylopectin chains consists of 20 - 25 glucose units, glycogen chains consist of 10 - 14 glucose units.
