"Webbrennin, 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. In animals that lack rennin, milk is coagulated by the … " - Protease enzyme and milk experiment

WebbChymosin, 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. If milk were not coagulated, it would rapidly flow through the stomach and ... Webbÿ In experiments A, B and D, you will determine the activities of trypsin, chymotrypsin and pepsin across the pH range 1 to 10 to illustrate their different pH dependencies. Substrate specificity of proteases Some proteases (exopeptidases) start at the end of a polypeptide chain and sequentially remove one amino acid at a time.
