Proteolytic enzymes, also known as proteases, are specialized proteins that break down other proteins into smaller peptides or amino acids. They play a crucial role in various biological processes, including digestion, cell signaling, and immune function. These enzymes are found in many organisms, including humans, where they help digest food in the stomach and small intestine. There are different types of proteolytic enzymes, categorized based on their mechanisms of action. Some common examples include trypsin, chymotrypsin, and pepsin. These enzymes are essential for maintaining proper health, as they facilitate nutrient absorption and help regulate various physiological functions in the body.
