DEFINITION:
- casein
-
A phosphoprotein, the principal protein of milk, the basis of curd and of cheese. It is precipitated from milk as a white amorphous substance by dilute acids, and redissolves on the addition of alkalis or of excess acid. Rennin (and other milk-clotting enzymes) influence the hydrolysis of casein to soluble paracasein, which in the presence of calcium (Ca2+) is converted to an insoluble curd (insoluble paracasein or calcium paracaseinate). Casein, usually in the form of its calcium, potassium, or sodium salts, is added to other ingredients of the diet to increase its protein content. NOTE: In British nomenclature, casein is called caseinogen, and paracasein is called casein.
