The kinetics of the reaction of acetaldehyde (AcH) with the alpha-amino group of several di- and tripeptides to form 2-methylimidazolidin-4-one adducts were determined at pH 7, 4, 37 degrees C, using reverse phase HPLC to separate peptides from adducts. The imidazolidin-4-one structure of the adducts was confirmed by 13C NMR spectroscopy. The reaction of val-gly-gly with AcH was shown to follow second-order
使用反相HPLC分离法测定乙醛(AcH)与几种二肽和三肽的α-氨基形成2-甲基咪唑啉丁-4-酮加成物的反应动力学,其pH为7、4、37摄氏度加合物中的肽。通过13C NMR光谱确认了加合物的咪唑啉丁-4-酮结构。Val-gly-gly与AcH的反应在两种反应物的较大浓度范围内均遵循二级动力学,k2 = 0.734 +/- 0.032 M(-1)min(-1)。在类似于酒精在慢性乙醇氧化过程中的肝脏条件下([Ach] o = 50-910 microm; [游离肽α-氨基] o = 1.5 mM),反应进行到有效地使所有AcH均具有被消耗了。N末端氨基酸的侧链显示对咪唑烷酮的形成速率没有显着影响。在60至100摄氏度下观察到val-gly-gly和AcH的咪唑啉酮加合物的分解。将Arrhenius曲线外推至37摄氏度,得出的K(obs)估计为0.002 h-1(t1 / 2约14天)。基于这
