Explanation:

The body requires a variety of macro nutrients for building blocks to fortify the body and keep it functioning. One of the important building blocks are amino acids that are derived from proteins. These are broken down in the stomach by protein digestion enzymes by amylase, proteases and hydrochloric acid.

In the even that the body has taken in too many units of protein this will be stored in the liver as glycogen. This is a form of "animal carbohydrate" or "animal sugar."

The glycogen stores will remain there for a reservoir for energy whenever the body requires it. In the event of overeating the body will store the glycogen in a more concentrated form, fat via the fatty acid synthesis pathway.
