Trypsin
Trypsin
Trypsin (/ˈtrɪpsɪn/) is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins. Trypsin is formed in the small intestine when its proenzyme form, the trypsinogen produced by the pancreas, is activated.
Etymology
The word "trypsin" comes from the Greek τρίψις, meaning "rubbing, friction, or wearing away," which may refer to the enzyme's ability to break down proteins.
Function
Trypsin is a proteolytic enzyme, meaning it breaks down proteins into their smaller peptide fragments and amino acids. This is a crucial part of the digestive process, as it allows the body to absorb and use the nutrients from the protein-rich foods we eat.
