应用

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。

生化/生理作用

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。

NADH provides electrons for aerobic ATP production. In cells deprived of oxygen or with impaired electron transport chain activity, NADH accumulation can be toxic. To minimize such toxicity, elevated NADH inhibits the classical NADH-producing pathways: glucose, glutamine, and fat oxidation.
