DescriptionNiacinamide, also known as nicotinamid or nicovit, belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. Niacinamide is a strong basic compound (based on its pKa). Niacinamide exists in all living species, ranging from bacteria to humans. Within yeast, niacinamide participates in a number of enzymatic reactions. In particular, niacinamide can be converted into nicotinic acid and ammonium through the action of the enzyme nicotinamidase. In addition, D-ribose and niacinamide can be biosynthesized from nicotinamide riboside; which is catalyzed by the enzyme uridine nucleosidase. In yeast, niacinamide is involved in the metabolic pathway called the nad metabolism pathway. Niacinamide is a potentially toxic compound.
