Chymotrypsin is a digestive enzyme produced in the pancreas. It plays a crucial role in breaking down proteins into smaller peptides in the small intestine. This enzyme is secreted in an inactive form called chymotrypsinogen and is activated by other enzymes, including trypsin. Chymotrypsin specifically targets peptide bonds adjacent to aromatic amino acids like phenylalanine, tyrosine, and tryptophan. Its activity is essential for proper digestion and nutrient absorption, helping the body utilize proteins from food effectively.
