What is NAD+?

NAD+ (Nicotinamide Adenine Dinucleotide — essential cellular coenzyme) is a Dinucleotide coenzyme (C₂₁H₂₇N₇O₁₄P₂). Essential redox coenzyme in oxidative phosphorylation (NADH/NAD+ cycling in ETC), substrate for all 7 sirtuins (SIRT1-7 deacylases), substrate for PARPs (DNA strand break repair), and CD38/cyclic ADP-ribose signalling. Declines 40–60% in most tissues with ageing.

Research Applications

Sirtuin Activation

SIRT1-7 NAD+-dependent deacylase activity, PGC-1α, FOXO3a

Mitochondrial Function

ETC complex I substrate cycling, ATP synthesis efficiency

DNA Repair

PARP1/2 activation — single-strand break repair and genome stability

NAD+ Decline Biology

Age-related NAD+ loss mechanisms — CD38, PARPs, sirtuins
