The hydrochloric acid present in our stomach dissolves bits of food and creates an acidic medium. In this acidic medium, the enzyme pepsinogen is converted to pepsin, which is a protein-digesting enzyme.
Digestive enzymes and their types
Digestive enzymes break down polymeric macromolecules into smaller building blocks to facilitate their absorption by the body. Thus, digestive enzymes convert the food into smaller molecules that your tissues, cells, and organs utilize for many metabolic functions.
- Amylase is defined as a digestive enzyme that breaks starch into small carbohydrate molecules.
- Protease enzyme breaks down protein into amino acids, which are its building blocks. The three main protease enzymes are trypsin, pepsin, and chymotrypsin.
- Lipase enzyme breaks down dietary fats into smaller molecules known as glycerol and fatty acids. In addition, a small quantity of lipase, known as gastric lipase, is produced by the cells of the stomach.
- Proteases are produced in the stomach and pancreas. The main ones are: pepsin, trypsin, chymotrypsin, carboxypeptidase A and carboxypeptidase B
