【Properties】 white or light yellow powder; no mold defeat smell; wet primer; aqueous acidic reaction. [Identification] take the product aqueous solution, add tannic acid, gallic acid or the majority of the heavy metal salt solution, which happened precipitation. 【Uses】 hydrolysis for fishmeal manufacturing and other proteins (such as soy protein), curd cheese manufacturing role (in combination with rennet), can also be used to prevent frozen beer haze. Pepsin is a digestive protease, the principal cells of the gastric mucosa in the stomach (gastric chief cell) secreted, functional food proteins into smaller peptide fragments. Pepsin precursors are called pepsinogen. An acidic protease. A protease extracted from animal gastric mucosa. Can decompose the peptide bond is formed by the aromatic amino acid or acidic amino acid in the protein, it can catalyze the hydrolysis of casein, immunoglobulin, histone, animal horns, nails and feathers of keratin, and catalytic plant protein such. Not, however, the role of the protein in the sperm protein, the keratin in the mane and sponge. In addition to the hydrolysis of natural proteins, but also to the hydrolysis of certain polypeptides and dipeptides. The optimum pH value of 1.5 to 2.0. Used as a digestive medicine etc.. Pepsin in the acidic environment has a high activity, and its optimum pH is about 3. In a solution of neutral or alkaline pH, pepsin occurs melting and loss of activity. The strains of pepsin extracted from the gastric mucosa of pigs, sheep or cattle. Usage: nutritional supplements, enzyme preparation. The pepsin manufacturers, pepsin price, the use of pepsin, pepsin nutritional supplements, enzymes, pepsin, pepsin wholesale. Welcome to the new and old customers to negotiate!
