These are the proteins that remain once the caseins have been precipitated from whole milk. In human milk the five principal constituents of whey are:

  • alpha-lactalbumin - a major source of essential amino acids.
  • albumin - has a nutritional role.
  • lactoferrin - iron binding agent - thus inhibits the growth of iron-dependent bacteria in the gastrointestinal tract.
  • lysozyme - may have an antibacterial role.
