ANATOMY

Detailed explanation-1: -rennin, also called chymosin, protein-digesting enzyme that curdles milk by transforming caseinogen into insoluble casein; it is found only in the fourth stomach of cud-chewing animals, such as cows. Its action extends the period in which milk is retained in the stomach of the young animal.

Detailed explanation-2: -When the milk reaches to stomach, the milk protein casein reacts with the stomach acid as well as the enzyme rennin. It is a proteolytic enzyme that is synthesized in the stomach. It coagulates the milk by reaction and forms curd. Rennin is mostly a proteolytic enzyme that is formed by the chief cells of the stomach.

Detailed explanation-3: -Chymosin, the major component of rennet (milk clotting enzyme), is an acid protease produced in the fourth stomach of milk-fed ruminants including goat and sheep in the form of an inactive precursor prochymosin.

Detailed explanation-4: -Chymosin, known also as rennin, is a proteolytic enzyme related to pepsin that synthesized by chief cells in the stomach of some animals. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal.

Detailed explanation-5: -Vignola (2002) defined milk coagulation as the destabilization of the casein micelles, which flocculate and aggregate to form a gel enclosing the soluble milk components. It can be caused by acidification, by the action of an enzyme or by a combination of the two.
