Superoxide radicals in the kinetics of nitroxide-inhibited oxidation of methyl linoleate in micelles

Resumo

The kinetics of the oxidation of methyl linoleate in micelles inhibited by stable nitroxides under the conditions of initiation by superoxide radicals was studied. Multiple breakdown of the oxidation chains was observed in this process. The antioxidant activity of nitroxides increased when the reduction potential of the oxoammonium cation/nitroxide pair decreased and their lipophilicity increased.
