lactalbumin

lactalbumin
The albumin fraction of milk. It contains two proteins: α- and β-l.; the former, minor l., interacts with galactosyl transferase to form lactose synthase which synthesizes lactose from d-glucose and UDP-galactose in milk production; β-l. is the chief whey protein in bovine milk; α-l. is the most heat-stable of the whey proteins.
