Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Pepsin is one of three principal protein-degrading enzymes in the
digestive system, the other two being chymotrypsin and trypsin. During
the process of digestion, these enzymes collaborate to break down
dietary proteins to their components, i.e., peptides and amino acids.
