Where Trypsin Is Found?

Trypsin is a serine protease of the digestive system produced in the pancreas as an inactive precursor, trypsinogen

trypsinogen
Cod trypsinogen I consists of 241 amino acid residues (about 26 kDa) with a signal peptide of 13 amino acids and a propeptide (activation peptide) of 6 amino acids. It is activated when the peptide bond between Arg (-1) and Ile 1 is cleaved which results in a molecular weight of about 24 kDa for cod trypsin I.

. It is then secreted into the small intestine, where enterokinase proteolytic cleavage activates it into trypsin.

Where is trypsin found and produced?

Trypsin is one of the best characterized serine proteinases. It has long been known that trypsin is produced as a zymogen (trypsinogen) in the acinar cells of the pancreas, is secreted into the duodenum, is activated into the mature form of trypsin by enterokinase, and functions as an essential food-digestive enzyme.

Is trypsin found in the small intestine?

In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen.
