What is Glycogen? What is its role in our body?

Glycogen is the storage form of glucose (sugar) in the body. It is a complex material made of individual glucose molecules linked together in long chains with many branches off the chains (just like a tree). Glycogen is mainly stored in the liver and muscle cells, but the kidneys and intestines also store some limited amounts of glycogen.

Metabolism is the process by which our body breaks down the food we eat and converts it to energy.
