ИСТИНА

Whey protein lactoferrin (LF) is one of the significant components of the protective complex of milk and is known as a polyfunctional protective factor. Lactoferrin is represented by two molecular forms: apo- and holo-lactoferrin. The main mechanism of the biological action of LF is based on the binding of trivalent iron (there are two Fe3+ of binding domains in its molecule). The active form of the protein is the iron-free molecular form (apo-LF). When saturated with iron, lactoferrin passes into a biologically inactive form - holo-LF. Lactoferrin in its active form has antibacterial, bifidogenic, antiviral, antifungal, antioxidant, antiulcer, antidisbacteriosis, anti-inflammatory, anti-carcinogenic, anti-tumor, immunomodulatory action, the ability to activate macrophages and functions as an iron carrier in an animal body.
