cyclic adp ​ribose

Cyclic ADP-ribose (cADPR) is an effective calcium mobilization second messenger, which is synthesized from NAD + by ADP-ribosyl cyclase. Cyclic ADP-ribose mainly increases cytosolic calcium through Ryanodine receptor-mediated endoplasmic reticulum release

Cyclic ADP-ribose ammonium (cADPR ammonium) is a powerful calcium mobilization second messenger synthesized from NAD+ by an ADP-ribosyl cyclase. It primarily raises cytosolic calcium levels through Ryanodine receptor-mediated release from the endoplasmic reticulum, while also facilitating extracellular influx through the opening of TRPM2 channels [1][2][3].

NADH 是一种可口服的还原型辅酶，也是 ADP-核糖基转移酶反应中 ADP-核糖单元的供体以及环状 ADP-核糖的前体。NADH 在能量代谢中担任再生电子供体角色，涉及过程包括糖酵解、β-氧化和三羧酸 (TCA) 循环。
