 English: pepsin. CAS :9001-75-6 enzyme activity: 3000U / g. 
 Properties White or light yellow powder; no mold smell defeat; have cited wet; aqueous acidic reaction. 
 Identification of this product in aqueous solution, add tannic acid, gallic acid, or the majority of heavy metal salt solution, precipitation occurs. 
 Purpose is mainly used for fishmeal production and other proteins (such as soy protein) hydrolysis, curd cheese manufactured in the role (in combination with rennet), can also be used to prevent cold beer cloudy. 
 Pepsin is a digestive protease from the stomach of the gastric chief cells (gastric chief cell) of the secretion function of the protein in food is broken down into smaller peptide fragments. Pepsin precursor called pepsinogen. An acidic protease. Extracted from animal mucosa of a protease. Can break down the protein in acidic amino acids by the aromatic amino acids or peptide bond formed, it can catalyze casein, globulin, histone, animal horns, nails and the keratin in feathers, and catalytic hydrolysis of plant protein. But it can not act on the sperm protein, keratin and mane of the sponge in the protein. In addition to the hydrolysis of natural protein, but also the hydrolysis of certain peptides and two peptides. The optimum pH value of 1.5 to 2.0. In medicine as a digestive agent. 
 Pepsin in the acidic environment with high activity, the optimum pH value of about 3. In neutral or alkaline pH of the solution, the solution will occur pepsin chain lost activity. The strains from pigs, sheep or cattle gastric pepsin extracted. Each 1g contains not less than 3800 units of protease activity.
