Pepsin functions to break down food proteins into peptides. Pepsin works as catalysts that speed up biochemical reactions in the process of protein digestion.
enzyme Pepsin
Researcher John N. Mills and Jordan Tang pepsin describes as "enzyme containing 327 amino acid residues in a single polypeptide chain."
Pepsin contains 21 different amino acids, with a total of 327 molecules composed of amino acids together to form proteins.
Amino Acid Pepsin Authors
Mills and Tang signed 21 amino acids that make up pepsin: lysine, histidine, arginine, aspartic acid, asparagine, threonine, serine, phosphoserine, glutamic acid, glutamine, proline, glycine, alanine, half-cystine, valine, methionine, isoleucine, leucine , tyrosine, phenylalanine, and tryptophan.
Digestive enzymes
Hydrochloric acid converts pepsinogen into pepsin, which in turn is used to break down proteins into peptides.
Pepsinogen production is stimulated by the hormone gastrin. To stay safe, protected by the gastric mucus so that it remains secure under acidic conditions and did not participate 'digested' by pepsin.
Biology Professor Michael Gregory of SUNY explained that pepsin cause injury to the wall of the stomach when the stomach stops secreting mucus.
