Casein ( or , from
Latin caseus, "cheese") is the name for a family of related
phosphoproteins (αS1, αS2, β, κ). These proteins are commonly found in mammalian
milk, making up 80% of the proteins in
cow milk and between 20
nd 45% of the proteins in
human milk. Casein has a wide variety of uses, from being a major component of
cheese, to use as a food additive, to a binder for safety matches. As a
food source, casein supplies
amino acids,
carbohydrates, and the two inorganic elements
calcium and
phosphorus.
