WebNov 9, 2024 · The highly toxic oxidative transformation of hemoglobin (Hb) to the ferryl state (HbFe4+) is known to occur in both in vitro and in vivo settings. We recently constructed … WebMethemoglobin results from oxidation of the iron moieties in hemoglobin from the ferrous (Fe2+) to the ferric (Fe 3+) state. Normal oxygenation of hemoglobin causes a partial transfer of an electron from the iron to the bound oxygen. Iron in this state thus resembles ferric iron and the oxygen resembles superoxide (O 2− ).
WebIncreased levels of methemoglobin are found in blood stains. Upon exiting the body, bloodstains transit from bright red to dark brown, which is attributed to oxidation of oxy-hemoglobin (HbO 2) to methemoglobin (met-Hb) and hemichrome (HC).
