The enzyme named pepsin is released by some chief cells that can be found in the stomach. This enzyme has the capability and the role of degrading food proteins into peptides, thus producing digestion. Discovered in 1836, pepsin was the first revealed enzyme and also the first that was crystallized.
Pepsinâs main function is to break down proteins that are found in protein rich foods such as meat, eggs etc. It breaks them into smaller pieces called polypeptides. Interesting thing about pepsin is that it breaks proteins only at certain points so that the protein is not digested completely to the amino acid level.epsinogen is a pro-form zymogen of pepsin. It is released in the stomach by its chief cells. This zymogen is activated by hydrochloric acid released from parietal cells in the stomach linings.
