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 intestines. In addition to their role in digestion, proteolytic enzymes are also used in various industries, such as food processing and pharmaceuticals. For example, they can tenderize meat or be used in enzyme replacement therapy for certain medical conditions. Their ability to break down proteins makes them valuable in both natural and industrial applications.
