Lactoferrin and iron ion affinity is very high, 250 ~ 300 times that of transferrin. Based on the differences of lactoferrin in combination with iron ion, it can be divided into three types: lack of iron, iron half-starved, and type and iron Quercetin Dihydrate Manufacturer saturation. Different types of lactoferrin has different ability to resist pap sterilization of thermal denaturation, the strongest type of iron saturation resistance, resistance to iron deficiency is most weak. Lactoferrin can not only combine Fe3 + and Fe2 +, can also be combined with Cu2 +, Mn2 +, Zn2 +. Lactoferrin can respond to a variety of physiological and environmental changes, so it is considered to be key components of innate defense system. Lactoferrin for a variety of bacteria, fungi, viruses and parasites, yeast showed strong antibacterial activity. It also has anti-inflammatory and anti-cancer activity, and Sex Enhancement Powder have a variety of enzyme function. Lactoferrin in maintaining cells play a key role in iron levels in the body. Lactoferrin was first discovered and biological function of extensive research is its bacteriostasis ability. Lactoferrin has a broad spectrum of gram-positive bacteria and gram-negative bacteria and fungi, can effectively inhibit e. coli, typhoid salmonella species, streptococcus, eosinophilic lung legionella bacteria, the growth of staphylococcus aureus. Give patients clinically lactoferrin oral treatment, reducing the gastrointestinal tract bacterial infections, but does not affect the growth of lactobacillus and bifidobacterium.
On the thermal stability of lactoferrin, the study found that 135 ℃ or 72 ℃ heat preservation 20 s insulation 8 s almost does not affect the heat treatment of lactoferrin iron binding capacity, but if prolonged treatment of the two kinds of temperature will reduce the iron binding capacity. 85 ℃ heat preservation 10 min heat treatment of strength also won't affect the antibacterial activity of lactoferrin. In addition, studies have shown that under the condition of pH2.0 or pH3.0, 120 ℃ after 5 min, lactoferrin is degraded but degradation products of bacteriostatic activity is higher Kava Root Extract than before treatment. This experimental results it was found that the existence of lactoferrin active peptides. Lactoferrin to gram-positive bacteria and gram-negative bacteria has bacteriostatic effect, but the stronger effect on gram-negative bacteria. The iron saturation of lactoferrin and negatively correlated with antibacterial sex. Environmental pH change lactoferrin inhibition of gram positive bacteria, had a little effects on gram-negative bacteria. When the pH is 7.5 ~ 8.0, bacteriostatic effect is best. Lactoferrin after under 70 ℃ of pasteurized bacteriostatic activity has no effect; HCO3 - concentration increased, to strengthen its bacteriostasis.
