Nicotinamide (niacinamide) is a form of vitamin B3 (niacin). Nicotinamide, (/ˌnɪkəˈtɪnəmaɪd/) also known as niacinamide, NAA, and nicotinic amide, is the amide of nicotinic acid (niacin). Nicotinamide is a water-soluble vitamin B.
Nicotinic acid is converted to nicotinamide in vivo, and, though the two are identical in their vitamin functions, nicotinamide does not have the same pharmacological and toxic effects as niacin, which occurs incidental to niacin's conversion. Nicotinamide does not reduce cholesterol or cause flushing, although it may be toxic to the liver at doses exceeding 3g/day in adults. In cells, niacin is incorporated into nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), although the pathways for nicotinic acid amide and nicotinic acid are very similar. NAD+ and NADP+ are coenzymes in a wide variety of enzymatic oxidation-reduction reactions. Commercial production of niacin and niacinamide (several thousand tons annually) is by hydrolysis or aminolysis of 3-cyanopyridine (nicotinonitrile).
