AS Biology Coursework 2002: Investigating the effect of temperature on the rate of reaction of the essence rennet Plan Rennet contains enzymes called chymosin, which have the property of clotting, or curding milk. Chymosins' coagulate the protein casein found in milk, forming solid curds. 0They firstly break down specific bonds in a glycopeptides found on the surface of soluble calcium caseinate that contain casein, leaving relatively insoluble calcium paracaseinate (unstable, denuded casein particles). These particles in the presence of calcium (2-) ions coagulate to form a continuous curd. This property of coagulating milk makes rennet a biological enzyme that is used industrially in the production of cheese, yogurt, and other diary products. There are many forms of rennet, derived from different sources using different methods. In this investigation I will be using calf rennet, this has been derived from the inner lining of the fourth stomach of a calf. Other forms include, Maxiren (100%...
