Question
What are glycogens? How it is different from starch?
✓
Answer
Glycogens : Carbohydrates stored in animal body in form of glycogen. It is also known as animal starch because its structure is similar to amylopection and is rather more highly branched. It is stored in silver, muscles and brain. When our body needs glucose, enzymes convert glycogen into glucose. On the other hand, starch is the mixture of amylose $(15-20 \%)$ which is water soluble and amylopectin (80-85\%) which is water insoluble compound. Both glycogen and amylopectin are branched polymers of $\alpha$-D-glucose. Starch is the main storage polysaccharide of plants.
