A product of the extracellular Nicotinamide phosphoribosyltransferase (eNAMPT) reaction and a key NAD+ intermediate. It ameliorates glucose intolerance by restoring NAD+ levels in HFD-induced T2D mice. It also enhances hepatic insulin sensitivity and restores gene expression related to oxidative stress, inflammatory response, and circadian rhythm, partly through SIRT1 activation. B-Nicotinamide mononucleotide (NMN) is used to study binding motifs within RNA aptamers and ribozyme activation processes involving B-nicotinamide mononucleotide (B-NMN)-activated RNA fragments.Beilstein Registry Number: 3570187 EC Number: 214-136-5 MDL number: MFCD00038748 PubChem Substance ID: 24897645Purity: ≥ 95%Form: White to off-white powderSolubility (50mg/ml, dH2O): Clear, colorless and complete
