beta-Lactoglobulin represents approximately
half of the total protein in bovine whey,
while human milk contains no beta-lactoglobulin.
Besides being a source of essential and
branched chain amino acids, a retinol-binding protein
has been identified within the beta-lactoglobulin
structure. This protein, a carrier of small
hydrophobic molecules including retinoic acid, has
the potential to modulate lymphatic responses
