Y Dai,P Chang,G Li,Y Lin,

The injury effects of O2-. and H2O2 on the hemoglobin were investigated. The results showed that the metal prosthetic group was injured by O2-. and H2O2, but the mechanism of O2-. and H2O2 effects was different. Through the charge neutralization O2-. destroying the static electrical interactions between prosthethic groups and amino acid residues, it thereby caused prosthetic group dropped. H2O2 had Fenton reaction with Fe2+ in prosthetic group, hence produced .OH. It can destroy the porphyrin structure at fixed point in short distance, so the prosthetic group was destroyed and non-reversible.
