Peroxyl radicals (ROO•), formed by reactions of molecular oxygen with carbon-centered radicals, are far more stable than either the carbon-centered radical or the related alkoxyl radicals (RO•). Peroxyl radicals typically have t1/2 of 7 s at 37 °C and can thus diffuse moderate distances in biological systems.
