Nicotinamide is a water-soluble component of the vitamin B complex group. In vivo, Nicotinamide is incorporated into nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). NAD and NADP function as coenzymes in a wide variety of enzymatic oxidation-reduction reactions essential for tissue respiration, lipid metabolism, and glycogenolysis.
Nicotinamide Adenine Dinucleotide. Nicotinamide adenine dinucleotide (NAD) is one of two main metabolically active forms of vitamin B-3. The other is NAD phosphate (NADP). NAD is a prominent coenzyme in the brain, where it helps generate the massive energy that the brain requires for its normal function.NAD is necessary for many stages of converting foods into energy and in alcohol metabolism.icotinamide adenine dinucleotide (NAD) is one of two main metabolically active forms of vitamin B-3.
