It is a primary electron carrier, cycling between NAD⁺ and NADH in glycolysis, the TCA cycle, and oxidative phosphorylation. Beyond redox roles it is a substrate for sirtuins and PARPs, linking it to research on cellular signaling, DNA-repair pathways, and metabolic regulation; it is a standard enzymology reagent and a focus of cellular-aging research. Research applications Cofactor/substrate in enzymatic and redox biochemistry assays Preclinical models of cellular energy metabolism Sirtuin/PARP and NAD⁺ salvage-pathway research Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
