NAD(53-84-9)|99% Purity|Research Grade Peptides|Purity tested by renowned testing laboratories

NAD+ (Nicotinamide Adenine Dinucleotide) is a ubiquitous coenzyme found in all living cells, playing a central role in cellular energy metabolism. It functions as an electron carrier in oxidation‑reduction reactions, accepting electrons to become NADH in catabolic pathways such as glycolysis, the TCA cycle, and mitochondrial electron‑transport‑chain activity. Beyond energy metabolism, NAD+ serves as a substrate for key regulatory enzymes including sirtuins (SIRT1‑7), poly(ADP‑ribose) polymerases (PARPs), and CD38/CD157 ectoenzymes, linking NAD+ levels to DNA repair, gene expression, circadian rhythms, and cellular aging‑related laboratory observations

As a research reagent, NAD+ is intended for in vitro and in vivo studies of cellular metabolism, mitochondrial function, sirtuin activation, DNA repair, aging, and neurodegenerative diseases. Research has shown that NAD+ levels decline with age, and boosting NAD+ through precursors or direct supplementation may improve metabolic health and extend lifespan in animal models.

• Energy Metabolism：NAD+ serves as the primary electron carrier in cellular respiration, accepting electrons from glycolysis and the TCA cycle to form NADH, which then delivers electrons to the electron transport chain for proton‑gradient‑driven ATP synthesis.
• Sirtuin Activation：NAD+ is an obligate co-substrate for sirtuins (SIRT1-7), a family of NAD+-dependent deacetylases that regulate gene expression, DNA repair, metabolism, and stress resistance. SIRT1, the most studied, deacetylates histones and transcription factors including p53, FOXO, and PGC-1α.
• DNA Repair：NAD+ is consumed by PARPs (poly(ADP-ribose) polymerases) during DNA damage repair. PARP-1, activated by DNA strand breaks, uses NAD+ to synthesize poly(ADP-ribose) chains that recruit repair machinery. High DNA damage can deplete cellular NAD+ pools, linking genomic instability to metabolic decline.
