Carboxypeptidases are enzymes that play a crucial role in digestion by breaking down proteins into smaller peptides and amino acids. They specifically target the carboxyl end of protein chains, removing terminal amino acids. These enzymes are produced in the pancreas and secreted into the small intestine, where they help in the final stages of protein digestion. These enzymes are part of a larger group known as peptidases, which includes various enzymes that cleave peptide bonds. Carboxypeptidases are essential for nutrient absorption, as they ensure that proteins are fully digested into their building blocks, amino acids, which can then be utilized by the body.
