NADP+ is the oxidized form of the electron donor nicotinamide adenine dinucleotide phosphate . It serves as a cofactor in various biological reactions. In addition, the balance between these reduced and oxidized forms plays key roles in diverse cellular functions, including cell survival, the maintenance of redox status, and intracellular signaling. For example, binding of NADP+ to β-subunits of Kv channels activates ion transport, whereas NADPH stabilizes channel inactivation. NADP+ is biosynthesized from NAD+ by NAD kinase, with ATP as the phosphoryl donor.
NADPH tetrasodium salt (Standard) 是一种可用于分析的标准物质,通常用作 NADPH tetrasodium salt 的研究和分析中参考的标准样品。NADPH tetrasodium salt 是电子受体烟酰胺腺嘌呤二核苷酸磷酸的还原形式,在各种生物反应中充当电子供体。NADPH tetrasodium salt 也是一种内源性铁死亡抑制剂。
