What is lactoferrin?

Isolated from Milk and whey, lactoferrin is a glycoprotein that binds to iron. Its unique structure, which consists of a single polypeptide chain with two binding sites for iron, explains its high affinity for iron. This crucial host defense protein exhibits considerable biological action even in modest amounts. This protein has numerous advantages, such as […]
