Application

β-烟酰胺腺嘌呤二核苷酸(NAD +)和β-烟酰胺腺嘌呤二核苷酸还原(NADH)包含辅酶氧化还原对(NAD +:NADH),参与广泛的酶催化氧化还原反应。 除了其氧化还原功能外,NAD +/NADH是ADP-核糖基转移酶(ADP-核糖基转移酶;聚(ADP-核糖)聚合酶)反应中的ADP-核糖单元的供体和环状ADP-核糖(ADP-核糖基环化酶)的前体。
作为一种试剂,NADH可用于酶循环测定,以扩大对低浓度含量的生物相关酶或代谢物活性的检测。

Biochem/physiol Actions

NADH是一种辅酶,其在糖酵解、氧化和柠檬酸循环(Krebs循环、TCA循环)等分解代谢过程中起着再生电子供体的作用。它也参与细胞信号事件,例如在DNA损伤反应过程中作为多聚(ADP-核糖)聚合酶(PARPs)的底物。NAD+/NADH依赖的去乙酰化酶在能量代谢过程中的应激反应中发挥关键作用,在癌症生物学、糖尿病和神经退行性疾病中具有重要意义。
作为一种试剂,NADH可用于酶循环测定,以扩大对低浓度含量的生物相关酶或代谢物活性的检测。
