Lactoferrin (LF), also known as lactotransferrin (LTF), is a multifunctional protein of the transferrin family. Lactoferrin is a globular glycoprotein with a molecular mass of about 80 kDa that is widely represented in various secretory fluids, such as milk, saliva, tears, and nasal secretions. Lactoferrin is also present in secondary granules of PMN and is secreted by some acinar cells. Lactoferrin can be purified from milk or produced recombinantly. Human colostrum ("first milk") has the highest concentration, followed by human milk, then cow milk (150 mg/L).
Lactoferrin and its protein degradation product, lactoferrin peptide, have a wide range of biological activities, including broad-spectrum antibacterial action, anti-inflammatory, inhibition of tumor cell growth and regulation of immune response, etc., and are considered as a new type of antibacterial and anticancer drug. Food and cosmetic additives with great development potential, such as the US Food and Drug Administration, have long allowed lactoferrin as a food additive for sports and functional foods. Lactoferrin is a constituent of the innate immune system. In addition to its primary function of binding and transporting iron ions, lactoferrin also has antibacterial, antiviral, antiparasitic, catalytic, anticancer, anti-allergic and radiation protection functions and attributes.
What is function of lactoferrin powder?
Lactoferrin is the composition material of the innate immune system proteins . In addition to the main functions of combining and transporting the iron , Lactoferrin also has the functions and attributes of antibacterial iron, antivirus, resistance to parasites, catalysis, cancer prevention and fighting against cancer, allergy and radiation protection.
