Niacin is a simple derivative of pyridine. Active forms of niacin are: Nicotinamide adenine dinucleotide (NAD+) Nicotinamide adenine dinucleotide phosphate (NADP+) Niacin is a precursor of coenzymes, nicotinamide adenine dinucleotide (NAD+) and nicotinamide adenine dinucleotide phosphate (NADP+). NAD+ and NADP+ are involved in various oxidation and reduction reactions. They are, therefore involved in many metabolic pathways of carbohydrate, lipid and protein.
