SKU: NAD-500MG   |   Category: Research Compounds

Nicotinamide adenine dinucleotide | Oxidized form | Coenzyme for redox and sirtuin research | ≥99% purity

NAD+ (nicotinamide adenine dinucleotide, oxidized form) is a critical pyridine dinucleotide coenzyme involved in cellular redox reactions, serving as an electron carrier in glycolysis, the TCA cycle, and oxidative phosphorylation. Beyond its bioenergetic role, NAD+ is a substrate for sirtuins (SIRT1-7), poly(ADP-ribose) polymerases (PARPs), and CD38/CD157 ecto-enzymes, making it central to research on aging biology, DNA damage response, and epigenetic regulation.

Research applications include sirtuin deacylase activity assays, PARP-1/2 enzyme kinetics, NAD+/NADH ratio quantification in cellular metabolic studies, investigation of NAD+ biosynthetic pathway enzymes (NAMPT, NMNAT), and supplementation-based research in cell culture models examining mitochondrial function and gene expression. The 500mg vial is suitable for multi-experiment workflows.
