Lactoferrin: A Multifaceted Glycoprotein in Milk

Lactoferrin, a multifaceted glycoprotein, is a key milk-borne carrier for iron and other trace metals important for infant nutrition.It also plays an important role in innate immunity with antibacterial and antiviral properties, as an anti-inflammatory agent, and an antioxidant.Lactoferrin is present in high concentrations in mammalian milk; it is often the most abundant protein in milk after casein.The highest concentrations are seen in colostrum at nearly 5 gm/L and then at 2-3 gm/L in mature milk.The current review highlights our understanding of lactoferrin's structure, properties, and possible clinical applications, offering insights for future research and the development of functional products.There are also possible uses in food, pharmaceuticals, and biotechnology industries.There is a need for serious, focused work.
