Unlike the peptides in the catalog, NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to cellular energy metabolism, and its research interest stems from two distinct roles.
Redox cofactor
NAD+ cycles between oxidized (NAD+) and reduced (NADH) forms, shuttling electrons through metabolic pathways such as glycolysis and the citric-acid cycle — the foundation of NAD+ in cellular research.
Signaling substrate
NAD+ is also consumed as a substrate by enzymes including sirtuins and PARPs, linking it to research on cellular stress responses and DNA-repair signaling — explored in NAD+ research applications.
Why it is studied
Because both roles connect to metabolic and aging-related pathways, NAD+ is a common cofactor in in-vitro research. Its origins are covered in NAD+ discovery and history.
