High pepsinogen
WebPepsinogen is a powerful and abundant protein digestive enzyme secreted by the gastric chief cells as a proenzyme and then converted by gastric acid in the gastric lumen to the active enzyme pepsin. The role of pepsin and its precursor in protein digestion was first described in the 19th century. WebPepsin Enzyme Structure Basically, proteins are large polymers that are joined by peptide bonds. The peptide bond is an amide linkage that joins the amino group of one amino acid to the carboxyl group of another. Proteins comprise several types of amino acids, with the difference being in the chemical nature of the side chain.
