Trypsin is a type of protease that is a serine proteolytic enzyme extracted from the pancreas of cows, sheep, and pigs. In vertebrates, it functions as a digestive enzyme. In the pancreas, the precursor of trypsin, trypsinogen, is synthesized and secreted as a component of pancreatic juice. It is restricted by enterokinase or trypsin and breaks down into activated trypsin. It is an endonuclease that can cleave the carboxyl groups in lysine and arginine residues of polypeptide chains. It not only functions as a digestive enzyme, but also limits the decomposition of precursors of other enzymes such as chymotrypsinogen, carboxypeptidase, and phospholipase, playing an activating role. It is the most specific protease and an indispensable tool in determining the amino acid arrangement of proteins.
Trypsin is a white or almost white powder that is easily soluble in water and insoluble in organic solvents such as chloroform, ethanol, and ether. At pH 1.8, boiling for a short period of time hardly deactivates the product
