摘要

研究了儿茶酚胺对Triton X-100胶束中亚油酸甲酯氧化的影响。确定儿茶酚胺在生理pH值7.4时不抑制氧化。抑制只有在超氧化物歧化酶存在或在较低的pH值水平下才有可能。产生这种效应的原因是苯酚和苯氧基的阴离子形式与氧相互作用，形成超氧阴离子自由基。在超氧化物歧化酶存在下，儿茶酚胺抑制系数的高值是由于所产生的正醌的反应导致OH基团的再生。

Antioxidant Activity of Catecholamines During the Oxidation of Methyl Linoleoate in Triton X-100 Micelles

The effect of catecholamines on the oxidation of methyl linoleate in Triton X-100 micelles is studied. It is established that catecholamines do not inhibit oxidation at a physiological pH value of 7.4. Inhibition is only possible in the presence of the superoxide dismutase enzyme or at lower pH levels. The reason for this effect is the interaction of anionic forms of phenols and phenoxyl radicals with oxygen to form superoxide anion radicals. The high values of the inhibition coefficients for catecholamines in the presence of superoxide dismutase are due to the reactions of the resulting orthoquinones, leading to the regeneration of OH groups.
