α-生育酚显著影响亚麻酸甲酯和亚麻酸甲酯自氧化过程中形成的过氧化物的分布。在这两种不饱和脂肪酸酯的自氧化中，具有反式、反式构型的共轭双键的单氢过氧化物的比例降低，直到高浓度的α-生育酚（5%）仅形成顺式、反式异构体。在亚麻酸甲酯的自氧化中，当5% α-过氧化氢-环二氧化物时，氢过氧-环二氧化物的比例降低，并且仅形成单氢过氧化物。存在生育酚。结果进行了讨论，在最近的研究结果有关的不饱和脂质的自氧化的机制。
.alpha.-Tocopherol substantially affects the distribution of peroxidic compounds formed during the autoxidation of methyl linolenate and methyl linolenate. In the autoxidation of both these unsaturated fatty acid esters the proportion of monohydroperoxides with conjugated double bonds in the trans, trans configuration is reduced until at high concentrations of .alpha.-tocopherol (5%) only cis, trans isomer are formed. In the autoxidation of methyl linolenate, the proportion of hydroperoxy-epidioxides is reduced and only monohydroperoxides are formed when 5% .alpha.-tocopherol is present. The results are discussed in terms of recent findings concerning the mechanism of the autoxidation of unsaturated lipids.
