NADP

NADP (CAS No.: 53-59-8) is a ubiquitous pyridine nucleotide coenzyme that functions as a central redox carrier in cellular metabolism, comprising nicotinamide mononucleotide linked via a pyrophosphate bridge to adenosine bisphosphate. It cycles between oxidized (NADP+) and reduced (NADPH) forms, thereby mediating electron transfer reactions essential for maintaining intracellular redox homeostasis and supporting anabolic biochemical pathways. NADPH serves as a primary electron donor in biosynthetic processes, including lipid and nucleic acid synthesis, and is critically involved in antioxidant defense systems through its role in regenerating reduced glutathione and modulating reactive oxygen species levels. This cofactor is also implicated in enzymatic systems such as NADPH oxidases, nitric oxide synthases, and various dehydrogenases, linking it to pathways governing oxidative stress responses, metabolic regulation, and inflammatory signaling. In vitro, NADP-dependent enzyme activities are typically studied across nanomolar to micromolar concentration ranges, depending on enzyme affinity and assay design. NADP is widely utilized in biochemical assays, metabolic flux analysis, and high-throughput screening platforms to investigate redox biology, enzyme kinetics, and cellular metabolism in both cell-based and cell-free systems, with experimental concentrations tailored to specific research objectives.
