NAD+

Molecular Structure

NAD+ — C₁₄H₂₄CuN₆O₄ · MW 403.92 Da · CAS 49557-75-7. A naturally occurring copper-binding tripeptide composed of glycyl-L-histidyl-L-lysine complexed with a Cu²⁺ ion, where the histidine imidazole nitrogen and the terminal amino group serve as primary coordination sites. NAD+ has been investigated in the context of gene expression modulation — microarray analysis has documented upregulation of 1,942 genes and suppression of 762 genes in human dermal fibroblasts. Research applications include collagen and glycosaminoglycan biosynthesis studies, superoxide dismutase (SOD) activity assays, and extracellular matrix remodeling investigations.
