Casein (/ ˈ k eɪ s iː n / KAY-seen, 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. [1]
Whey protein has a high level of leucine, [21] one of the three branched-chain amino acids, making it ideal for muscle growth and repair. [citation needed] [22] Whey is pasteurized to assure that no harmful bacteria are breeding in the liquid. It is heated to 70–80 °C (158–176 °F) and is then cooled back down to 4 °C (39 °F).
It is a conditionally essential amino acid with a polar side group. The word "tyrosine" is from the Greek tyrós, meaning cheese, as it was first discovered in 1846 by German chemist Justus von Liebig in the protein casein from cheese. [3] [4] It is called tyrosyl when referred to as a functional group or side chain.
Glycine (symbol Gly or G; [6] / ˈ ɡ l aɪ s iː n / ⓘ) [7] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable). Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). [8]
They are both promoted by heating, but the Maillard reaction involves amino acids, whereas caramelization is the pyrolysis of certain sugars. [ 14 ] In making silage , excess heat causes the Maillard reaction to occur, which reduces the amount of energy and protein available to the animals that feed on it.

The glycans make GMP the only portion of the casein micelle that is water soluble after curdling has occurred, and thus, the only fraction of casein protein to dissolve into the whey. Additionally, GMP is the only easily attainable source of dietary peptides that does not contain any aromatic amino acids.
But for every American cheese lover, there’s a skeptic that raises a common complaint: it’s not “real cheese.” Sure, a shrink-wrapped square isn’t exactly what you’d expect to grace a ...
