9,10-epoxy-13-hydroxy-11-octadecenoate (MeLEPOH), and methyl 9,10-epoxy-13-oxo-11-octadecenoate (MeLEPCO) with phenylalanine was studied to determine the comparative reactivity of primary, secondary, and tertiary lipid oxidation products in the Strecker degradation of amino acids. All assayed lipids were able to degrade the amino acid to a high extent, although the lipid reactivity decreased slightly
13-氢过氧十八烷基-9,11-二烯酸甲酯(MeLOOH),13-氢过氧十八烷基-9,11,15-三烯酸甲酯(MeLnOOH),13-羟基十八烷基-9,11-二烯酸甲酯(MeLOH),13-甲基含苯丙氨酸的oxooctadeca-9,11-dienoate(MeLCO),9,10-环氧13-hydroxy-11-octadecenoate甲基(MeLEPOH)和9,10-环氧13-oxo-11-octadecenoate甲基(MeLEPCO)与苯丙氨酸为了确定在氨基酸的Strecker降解中一级,二级和三级脂质氧化产物的比较反应性,我们进行了研究。尽管脂质反应性按以下顺序略有降低,但所有测定的脂质都能够高度降解氨基酸:MeLEPCO>或= MeLCO> MeLEPOH>或= MeLOH> MeLOOH大约= MeLnOOH。这些数据证实了许多脂质氧化产物具有通过Strecker型机制降解氨
