Trypsin is an enzyme that plays a crucial role in digestion. It belongs to a class of enzymes called proteases, which break down proteins into smaller peptides and amino acids. Trypsin is produced in the pancreas as an inactive precursor called trypsinogen, which is then activated in the small intestine by another enzyme called enterokinase.

Once activated, trypsin catalyzes the hydrolysis of peptide bonds in proteins, specifically targeting the carboxyl side of the amino acids lysine and arginine. This process is essential for the digestion of proteins into smaller peptides and amino acids, which can be absorbed by the intestines for nutrient uptake.

Trypsin is also used widely in biochemical research and biotechnology, particularly in protein analysis and manipulation. Its ability to selectively cleave peptide bonds makes it a valuable tool for studying protein structure and function.
