The affinity between lactoferrin and iron ion is very high, which is 250 to 300 times that of transferrin. According to the difference of lactoferrin binding iron ions, it can be divided into three types: iron deficiency type, iron semi-satiation type and iron saturated type. Different types of lactoferrin have different ability to resist pasteurization thermal denaturation, in which iron saturated type resistance is strong, iron deficiency type resistance is weak. Lactoferrin can bind not only Fe3+ and Fe2+, but also Cu2+, Mn2+ and Zn2+.
