描述
A permanganate is a chemical compound that contains the permanganate ion (MnO4-). Because manganese is in the +7 oxidation state, the permanganate ion is a strong oxidizer. Permanganates are salts of permanganic acid. Permanganate is a strong oxidizer, and similar to perchlorate. Being a strong oxidizer it is in common use in qualitative analysis experiments involving redox reactions (permanganometry). (wikipedia)
Various anions interact with human serum transferrin to the concomitant binding of iron and a synergistic anion to form the transferrin-anion-iron complex. In vitro, permanganate was found to partially inactivate transferrin. Transferrin treated with a 3:1 molar ratio of permanganate to active sites lost 74 or 67% of its iron-binding capacity, respectively. (PMID: 3028261)
In the presence of permanganate, Mn3+ was formed and chelated by transferrin at physiological pH in cows and goats. Manganese in the divalent state, either free as Mn2+ or bound to alpha2-macroglobulin, is removed from blood plasma very efficiently by the liver. However, the manganic-transferrin complex normally found in circulation is not rapidly removed from plasma. The liver can remove large amounts of excess manganous manganese which it presumably excretes; the small essential fraction of the manganese absorbed is oxidized to the trivalent state and bound to transferrin.
