Peroxidation of an unsaturated fatty acyl chain is initiated by a hydroxyl radical (OH·) or an acyl peroxyl radical (R·). Tocochromanols scavenge acyl peroxyl radicals and therefore minimize their reaction with further acyl chains. Details of the tocochromanol oxidation products are not shown, but most of these can be converted back to tocochromanol.
