Pepsin enzyme is a type of protease which catalyses the breakdown of proteins into smaller peptide chains. In humans pepsin is secreted with gastric juice in the stomach which helps in digestion of proteins present in meat, egg, seeds or dairy products. Pepsin requires an acidic environment for protein catabolism.

Functional properties:

pH: 1.5 - 2

Temperature: 37 - 40°C
