Y1 - 2022 N1 - T2 - Current Medical Diagnosis & Treatment 2022 AB - “Niacin” is a generic term for nicotinic acid and other derivatives with similar nutritional activity. Unlike most other vitamins, niacin can be synthesized from the amino acid tryptophan. Niacin is an essential component of the co-enzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are involved in many oxidation-reduction reactions. The major food sources of niacin are proteins containing tryptophan and numerous cereals, vegetables, and dairy products.
