Gastric pepsin function

http://api.3m.com/what+activates+pepsin Pepsin /ˈpɛpsɪn/ is an endopeptidase that breaks down proteins into smaller peptides. It is produced in the gastric chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food. Pepsin is an aspartic protease, using a catalytic aspartate in its active site.

Did you know?

WebPepsin's role in the stomach is to digest proteins through the hydrolysis of peptide bonds (1). At the optimal pH of 2, pepsin physiologically exists in monomeric form. At higher pH values of 4.5-6, however, aggregates and possible oligomers have been observed (2).

WebJan 7, 2024 · One of the important functions of gastric acid is to activate pepsinogen. Pepsinogen is secreted by the stomach wall and then turned into pepsin by gastric acid. Digestion is then initiated through proteolysis. The amount of pepsin produced is directly correlated to the amount of high-protein foods consumed. WebIn the epithelium, gastric pits lead to gastric glands that secrete gastric juice. The gastric glands (one gland is shown enlarged on the right) contain different types of cells that secrete a variety of enzymes, including hydrochloride acid, which activates the protein-digesting enzyme pepsin.

WebGastric juice contains three substances: hydrochloric acid, enzyme pepsin and mucus. Their functions are: Hydrochloric acid in the stomach is used to make the medium acidic to facilitate the action of the enzyme pepsin and to kill germs if any. Enzyme pepsin digests proteins to convert them into peptones. http://www.vivo.colostate.edu/hbooks/pathphys/digestion/stomach/secretion.html

WebThe breakdown of protein begins in the stomach through the actions of HCl and the enzyme pepsin. During infancy, gastric glands also produce rennin, an enzyme that helps digest milk protein. Its numerous digestive functions notwithstanding, there is only one stomach function necessary to life: the production of intrinsic factor.

WebJun 8, 2024 · Pepsin Pearls Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.
