NAD+ 500mg

Nicotinamide Adenine Dinucleotide (NAD+), in its biologically active oxidized state, is a cornerstone coenzyme integral to cellular metabolism, formally designated as β-Nicotinamide Adenine Dinucleotide. Its complete chemical nomenclature is 1-(β-D-ribofuranosyl)nicotinamide-5′-diphospho-5′-(adenosine), delineating a sophisticated structure: a nicotinamide moiety tethered to a β-D-ribose sugar via a glycosidic bond, linked through a pyrophosphate bridge to an adenosine unit comprising adenine and a second ribose sugar. With a molecular weight of approximately 663.4 Da, NAD+ features two nucleotide components connected by diphosphate ester bonds, enabling its dynamic interconversion with NADH in redox reactions. This architectural intricacy underpins its multifaceted roles in energy transduction, genomic stability, and intercellular signaling, distinguishing it as a pivotal modulator across eukaryotic and prokaryotic systems.
