Product type
Trypsin is a serine protease enzyme that plays a crucial role in the digestion of proteins in the gastrointestinal tract. It is produced from the pancreas of various animals, typically porcine or bovine sources, and is commonly used in laboratory and pharmaceutical applications. Trypsin catalyzes the hydrolysis of peptide bonds, specifically targeting lysine and arginine residues, which makes it essential for protein digestion and processing.
