Starch is a large molecule made up of lots of smaller glucose molecules joined together. Glycogen is a large carbohydrate molecule like starch. It is also made up of glucose molecules joined together. Animals store glucose as glycogen in our liver and muscles, our body turns glycogen into glucose when structure and function of carbohydrates need it for energy.
