NAD+ (Nicotinamide Adenine Dinucleotide)

Research Background

NAD+ is a fundamental coenzyme involved in cellular electron transfer reactions and serves as a substrate for numerous enzymatic processes. NAD+ has been investigated in research literature across several scientific contexts:

• Mitochondrial biology research — investigations into NAD+ involvement in oxidative phosphorylation, electron transport chain function, and cellular energy production pathways
• Sirtuin enzymology — extensive research on NAD+-dependent sirtuin proteins (SIRT1-SIRT7) and their roles in cellular regulatory pathways
• PARP enzymology research — studies examining poly(ADP-ribose) polymerase enzymes and their NAD+-consuming reactions in cellular biology
• CD38 and NAD+ metabolism research — investigations into NAD+ degradation pathways and cellular NAD+ homeostasis
• Cellular aging research — research literature examining NAD+ levels across cellular aging models and tissue contexts
• Cellular redox biology — research on NAD+/NADH ratio dynamics in cellular metabolic states

NAD+ research has expanded substantially over the past two decades, with peer-reviewed literature published across high-impact journals including Cell, Nature, and Science. Foundational research is available through PubMed (pubmed.ncbi.nlm.nih.gov) and the National Institutes of Health’s PMC database (pmc.ncbi.nlm.nih.gov), where researchers can access peer-reviewed studies on NAD+ cellular biology, including work by leading research groups including Sinclair et al., Imai et al., and Verdin et al. on cellular NAD+ biology
