Dissection of the radical reactions linked to fetal hemoglobin reveals enhanced pseudoperoxidase activity

In the presence of excess hydrogen peroxide (H(2)O(2)), ferrous (Fe(+2)) human hemoglobin (Hb) (α2β2) undergoes a rapid conversion to a higher oxidation ferryl state (Fe(+4)) which rapidly autoreduces back to the ferric form (Fe(+3)) as H(2)O(2) is consumed in the reaction. In the presence of additi...
