Nicotinic acid, [a] or niacin, [b] is an organic compound and a vitamer of vitamin B 3, an essential human nutrient. [ 4 ] [ 5 ] It is produced by plants and animals from the amino acid tryptophan . [ 6 ]
Vitamin B 3, colloquially referred to as niacin, is a vitamin family that includes three forms, or vitamers: nicotinic acid (niacin), nicotinamide (niacinamide), and nicotinamide riboside. [1] [2] All three forms of vitamin B 3 are converted within the body to nicotinamide adenine dinucleotide (NAD).
While nicotinic acid (niacin) may be used for this purpose, nicotinamide has the benefit of not causing skin flushing. [4] As a cream, it is used to treat acne , and has been observed in clinical studies to improve the appearance of aging skin by reducing hyperpigmentation and redness.
Niacin: Niacin is composed of two structures: nicotinic acid and nicotinamide. There are two co-enzyme forms of niacin: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Both play an important role in energy transfer reactions in the metabolism of glucose, fat and alcohol. [13]
The three vitamin precursors used in these salvage metabolic pathways are nicotinic acid (NA), nicotinamide (Nam) and nicotinamide riboside (NR). [6] These compounds can be taken up from the diet and are termed vitamin B 3 or niacin. However, these compounds are also produced within cells and by digestion of cellular NAD +.
Third, it may be caused by excess leucine, as it inhibits quinolinate phosphoribosyl transferase (QPRT) and inhibits the formation of nicotinic acid to nicotinamide mononucleotide (NMN) causing pellagra-like symptoms to occur. [9] Some conditions can prevent the absorption of dietary niacin or tryptophan and lead to pellagra.
A pyridinecarboxylic acid is any member of a group of organic compounds which are monocarboxylic derivatives of pyridine. Pyridinecarboxylic acid comes in three isomers: Picolinic acid (2-pyridinecarboxylic acid) Nicotinic acid (3-pyridinecarboxylic acid), also known as Niacin; Isonicotinic acid (4-pyridinecarboxylic acid)
Nicotinamide riboside (NR) is now known to be an NAD+ precursor, involved in the biosynthetic pathways that convert B3 vitamins into NAD+. NAD+ is primarily synthesized in mammals de novo from tryptophan, through the Priess-Handler pathway from nicotinic acid (NA) or via a salvage pathway from nicotinamide (NAM).
