Facts About Enzymes
- There are three different types of enzymes - digestive, metabolic, and food enzymes.
- Enzymes have a part in digestion, in the breaking down of vitamins or nutrients that you ingest, in building cells, and in reactions that transform energy into a usable source for the body.
- Some of the enzymes that are vital to the digestive process include pepsin, and trypsin which help break down proteins in the digestive track, and convert them into amino acids.
- Enzymes are organic compounds that are composed of amino acids.
An example of an enzyme is a digestive enzyme such as pepsin.
