What is pepsini?

Pepsin is an enzyme that is produced by the stomach and is involved in the process of digestion. It is a type of protease enzyme that breaks down proteins into smaller polypeptides and amino acids that can be easily absorbed by the body. Pepsin works optimally at a low pH, which is why it is found only in the stomach, which has a highly acidic environment. The production of pepsin is regulated by gastrin, a hormone that is released in response to the presence of food in the stomach. Pepsin is an important enzyme in the digestive process and is essential for the breakdown of protein-rich foods like meat, fish, and eggs.
