What is a Chymosin

What is a Chymosin? For many people, the curd may be unfamiliar, and here's the introduction to it:

Rennet is an earliest before weaning calf aspartic protease, found in the stomach can be single-mindedly cutting kappa - predominate in milk casein peptide bond between Phe105 - Met106, destroy the casein micelle curdled milk, rennet curds and protein hydrolysis ability makes it formed in the cheese production structure and special flavor of key enzymes, has been widely used in the production of cheese and yogurt.

Rennet curd function is divided into two steps: the first step is to enzyme hydrolysis specificity of milk in the kappa - casein polypeptide chain Phe105 - predominate Met106 peptide bond between the formation of stable vice kappa - casein predominate and hydrophilic sugar giant peptide; The second step is when the total kappa - predominate the hydrolysis of casein dropped about 80%, in the presence of calcium ions through the formation of chemical bond is formed between the casein micelle clot or coagulation of milk. This is because the kappa-casein molecule is on the surface of the casein micelle, which is connected by the interaction between the hydrophobic bond and the calcium phosphate
