Mammalian proteins

Casein ( ; from Latin caseus, 'cheese') is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.

protein supplement from milk

β-Lactoglobulin (beta-lactoglobulin, BLG, Bos d 5) is the major whey protein of cow and sheep's milk (~3 g/L), and is also present in many other mammalian species; a notable exception being humans. Its structure, properties and biological role have been reviewed many times. BLG is considered to be a milk allergen.

α-lactalbumin, also known as alpha-lactalbumin and LALBA, is a protein that in humans is encoded by the LALBA gene.

serum albumin protein derived from cows

secretoglobin protein

Lactalbumin, also known as "whey protein", is the albumin contained in milk and obtained from whey. Lactalbumin is found in the milk of many mammals. There are alpha and beta lactalbumins; both are contained in milk.
