DescriptionNicotinamide riboside, also known as N-ribosylnicotinamide or SRT-647, belongs to the class of organic compounds known as glycosylamines. Glycosylamines are compounds consisting of an amine with a beta-N-glycosidic bond to a carbohydrate, thus forming a cyclic hemiaminal ether bond (alpha-amino ether). Nicotinamide riboside is an extremely weak basic (essentially neutral) compound (based on its pKa). Nicotinamide riboside exists in all living species, ranging from bacteria to humans. Within yeast, nicotinamide riboside participates in a number of enzymatic reactions. In particular, nicotinamide riboside can be converted into nicotinamide ribotide through its interaction with the enzyme nicotinamide riboside kinase. In addition, nicotinamide riboside can be converted into D-ribose and niacinamide through its interaction with the enzyme uridine nucleosidase. In yeast, nicotinamide riboside is involved in the metabolic pathway called the nad metabolism pathway.
