Kinetics of the reduction of nitroxides with cysteine in the presence of a source of superoxide radicals was studied. The reactivity of nitroxides in this process is determined by the reduction potential of the N-oxoammonium cation / nitroxide pair. The rate-limiting step of the reaction is the nitroxide oxidation by the hydroperoxyl radical to the N-oxoammonium cation.

氮氧化物与半胱氨酸的超氧化物引发反应动力学

研究了在超氧自由基源存在下用半胱氨酸还原氮氧化物的动力学。该过程中氮氧化物的反应性由 N-氧铵阳离子/氮氧化物对的还原电位决定。该反应的限速步骤是氢过氧自由基将氮氧化物氧化为 N-氧铵阳离子。
