Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in all living cells and central to redox reactions in cellular metabolism, functioning as an electron carrier in the mitochondrial electron transport chain and as a substrate for NAD+-consuming enzymes including sirtuins (SIRTs), poly(ADP-ribose) polymerases (PARPs), and cyclic ADP-ribose synthases (CD38/CD157).
Research interest in NAD+ has grown significantly following the characterization of sirtuin-dependent deacetylase activity and the discovery that NAD+ levels decline in aging tissues in animal models. In vitro studies have used exogenous NAD+ supplementation to examine sirtuin activation, mitochondrial biogenesis markers (PGC-1α), and DNA repair pathway activity in various cell lines.
As a fundamental coenzyme, NAD+ is used as a research tool in a wide range of biochemical assays, including enzyme kinetics studies, NAD+/NADH ratio measurements, and pathway-specific metabolomics experiments. PeptiFy Labs supplies NAD+ at 99%+ purity with third-party COA documentation for each batch.
