Alpha-lactalbumin Overview

Alpha-lactalbumin is a small, globular protein found in the whey fraction of milk. It plays a crucial role in lactose synthesis by modulating β1,4-galactosyltransferase. It is a rich source of essential amino acids, particularly tryptophan, and has potential applications in infant nutrition, muscle health, and neurological function support. The molten globule form complexed with oleic acid (HAMLET) exhibits tumoricidal activity.
