A previously unreported metabolite of the mammalian phytanic acid breakdown pathway, 2-oxophytanic acid, was isolated and analysed by mass spectrometry. The metabolic origin of the 2-oxoacid is the oxidation by a rat kidney peroxisomal H2O2-generating oxidase of L-2-hydroxyphytanic acid, a well-established intermediate in phytanic acid alpha-oxidation.
分离了以前未报道的哺乳动物植酸分解途径的代谢物2-氧代苯甲酸,并通过质谱进行了分析。2-含氧酸的代谢起源是大鼠肾脏过氧化物酶体过氧化H2O2产生的L-2-羟基植酸的氧化酶的氧化作用,而L-2-羟基植酸是植酸α-氧化中公认的中间体。
