reaction. In the present study, the formation pathway of the dideoxyosone N6-(2,3-dihydroxy-5,6-dioxohexyl)- l -lysine is shown. To elucidate the formation of this glucose-derived dideoxyosone d -lactose (O-β- d -galp-(1 → 4)- d -glcp) and d -glucose-6-phosphate were incubated with lysine in the presence of the trapping reagent o-phenylenediamine (OPD). Synthesis and unequivocal structural characterization
摘要共价交联蛋白是由晚期美拉德反应引起的主要修饰。在本研究中,显示了双脱氧肌松N6-(2,3-二羟基-5,6-二氧己基)-1-赖氨酸的形成途径。为了阐明这种葡萄糖衍生的双脱氧肌松d-乳糖(O-β-d-galp-(1→4)-d-glcp)的形成,将d-葡萄糖-6-磷酸与赖氨酸在诱集下孵育试剂邻苯二胺(OPD)。报道了双脱氧肌松N6-(5,6-二羟基-2,3-二氧己基)-1-赖氨酸和N6-(2,3-二羟基-4,5-二氧己基)-1的喹喔啉的合成和明确的结构表征。 -赖氨酸。另外,合成了衍生自d-赤藓糖,d-甘油-d-甘露庚糖和d-葡萄糖-1-talooctose的二羰基化合物并对其结构进行了表征。
