Abstract:
Activated metmyoglobin (MetMb) by H2O2 initiates oxidation of microsomal unsaturated fatty acids, β-carotene and methional but not formate. Lipid peroxidation by activated MetMb was not inhibited by catalase. The activated species which initiaes lipid peroxidation appears to be a porphyrin cation radical, P{dot minus} + FeIV=O, and not a hydroxyl radical. © 1985 American Oil Chemists' Society.
