WebPepsinogens consist of a single polypeptide chain with molecular weight of approximately 42,000 Da. Pepsinogens are mainly synthesized and secreted by the gastric chief cells of the human stomach before being converted into the proteolytic enzyme pepsin, which is crucial for the digestive processes in the stomach. WebPepsin is one example of a group of enzymes termed "acid proteases." In the case of pepsin, this name is doubly appropriate. Pepsin works its best in strong hydrochloric acid. But the similarity with the other enzymes pictured here refers to a second type of acid. The active site of the acid proteases rely on two acidic aspartate amino acids ...

Pepsin Enzyme: Structure, Function, and Important Facts
WebMar 6, 2024 · HCl is necessary for the conversion of inactive pepsinogen to active pepsin, which helps with protein digestion in the stomach and the release of cobalamin (vitamin B12) from its salivary R-protein carrier. ... 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 … See more Pepsin was one of the first enzymes to be discovered, by Theodor Schwann in 1836. Schwann coined its name from the Greek word πέψις pepsis, meaning "digestion" (from πέπτειν peptein "to digest"). An acidic substance … See more Pepsin is most active in acidic environments between pH 1.5 to 2.5. Accordingly, its primary site of synthesis and activity is in the stomach (pH 1.5 to 2). In humans the … See more Pepsin may be inhibited by high pH (see Activity and stability) or by inhibitor compounds. Pepstatin is a low molecular weight compound and potently inhibitor specific for acid proteases with an inhibitory dissociation constant (Ki) of about 10 M for … See more • The MEROPS online database for peptidases and their inhibitors: Pepsin A A01.001, Pepsin B A01.002, Pepsin C (Gastricsin) A01.003 • Pepsin+A at the U.S. National Library of … See more Pepsin is expressed as a zymogen called pepsinogen, whose primary structure has an additional 44 amino acids compared to the active enzyme. In the stomach, … See more Pepsin is one of the primary causes of mucosal damage during laryngopharyngeal reflux.
