What type of protein is in milk?

Casein and whey protein are the major proteins of milk. Casein constitutes approximately 80%(29.5 g/L) of the total protein in bovine milk, and whey protein accounts for about 20% (6.3 g/L) (19-21). Casein is chiefly phosphate-conjugated and mainly consists of calcium phosphate- micelle complexes (20).
