1 The results show that, singly or in combination, bicarbonate, orthophosphate, citrate, apo-transferrin, and/or albumin have less than one-tenth of the ability to enhance the oxidation of Fe(II) compared to the serum enzyme, ceruloplasmin. ammonium ferrous sulfate ceruloplasmin Homo sapiens
2 Whereas ceruloplasmin produces a 4:1 ratio of Fe(II) oxidized to oxygen utilized, the non-enzymic components yield a 2:1 or 3.09:1 ratio. ammonium ferrous sulfate ceruloplasmin Homo sapiens
3 These data support the role of ceruloplasmin as an antioxidant that prevents the formation of the intermediate active oxygen species O 2 (-) and H2O 2 ( ) through the Fe(II) auto-oxidation reaction.A hitherto unrecognized factor in the control of nonenzymic oxidation of Fe(II) was serum albumin. ammonium ferrous sulfate ceruloplasmin Homo sapiens
4 These data support the role of ceruloplasmin as an antioxidant that prevents the formation of the intermediate active oxygen species O 2 (-) and H2O 2 ( ) through the Fe(II) auto-oxidation reaction.A hitherto unrecognized factor in the control of nonenzymic oxidation of Fe(II) was serum albumin. ammonium ferrous sulfate ceruloplasmin Homo sapiens
5 The addition of ceruloplasmin effected up to a 44 x increase in the rate of Fe(II) oxidation and Fe(III)-transferrin formation even in the presence of 0.60 mM albumin. ammonium ferrous sulfate ceruloplasmin Homo sapiens
