Milk is a white liquid produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals before they are able to digest other types of food.
Milk contains two proteins: casein and whey. Casein proteins are primarily in the curd of the milk, which is the hard portion of milk that forms when it curdles. Curd is the portion of milk that is used to make cheese. Whey is the portion of the milk that remains liquid after it curdles.
