Caption: Pepsin enzyme. Computer graphic of the protein- digesting enzyme pepsin. It is a protease enzyme that is secreted as part of gastric juice into the stomach in an inactive form known as pepsinogen. When it comes into contact with hydrochloric acid it is converted into the active form that hydrolyses proteins into smaller peptones. Each polypetide chain that makes up the molecule is assigned a different colour, as seen.
