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.

Cysteinylglycine TFA is an endogenous metabolite. It is used in disease diagnosis.

Palmitoyl L-Carnitine-d3 Hydrochloride是棕榈酰 L-肉碱的氘代衍生物。棕榈酰 L-肉碱是一种长链酰基肉碱，由棕榈酸和肉碱缩合而成，在线粒体脂肪酸 β-氧化和能量代谢中起关键作用。在病理状态下（如心肌缺血），棕榈酰 L-肉碱会在细胞膜内积聚。研究表明，它能改变膜脂环境并调节 KATP 通路，从而影响心肌细胞的电生理特性。作为氘代标记物，该化合物主要在基于质谱（LC-MS/MS）的定量分析中用作内标，利用氘代诱导的药代动力学动力学同位素效应（KIE）来提高检测的精确度。
