For bodybuilders, whey protein provides amino acids used to aid in muscle recovery. [15] Whey protein is derived from the process of making cheese from milk. There are three types of whey protein: whey concentrate, whey isolate, and whey hydrolysate. Whey concentrate is 29–89% protein by weight whereas whey isolate is 90%+ protein by weight.

The major protein in whey is β-lactoglobulin, followed by α-lactalbumin (β-lactoglobulin ≈ 65%, α-lactalbumin ≈ 25%, serum albumin ≈ 8%, other ≈ 2%). β-lactoglobulin is a lipocalin protein, and can bind many hydrophobic molecules, suggesting a role in their transport. β-lactoglobulin has also been shown to be able to bind iron via siderophores [7 ...
