The enzyme named pepsin is released by some chief cells that can be found in the stomach.

Discovered in 1836, pepsin was the first revealed enzyme and also the first that was crystallized.
Click on the interactive links below. Pepsin is a protease (protein-digesting enzyme), which is active in the stomach. The porcine pepsin molecule displayed here consists of 327 amino acid residues - 2797 atoms, ignoring hydrogen atoms, but this also includes oxygens from 375 water molecules!lick on the interactive links below.
