Translations
Peptone
peptone[′pep‚tōn] (biochemistry) A water-soluble mixture of proteoses and amino acids derived from albumin, meat, or milk; used as a nutrient and to prepare nutrient media for bacteriology. Peptone a product formed by the partial hydrolysis of proteins and consisting chiefly of a mixture of various polypeptides and also containing dipeptides, tripeptides, and free amino acids. Peptones are formed by the action of proteolytic enzymes in gastric and pancreatic juices (pepsin, trypsin) on proteins or by careful hydrolysis of proteins in acid or alkaline solutions. The composition and name of a peptone depend on the type of protein from which the peptone is derived. Thus, there are meat peptones, fish peptones egg peptones, and others. Peptones are used in microbiology for the preparation of nutrient media. peptone
