Niacin, also known as nicotinic acid, 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 ]
Example of a label showing the amount of niacin (Vitamin B3), and specifying to be niacinamide in the ingredient section.. The United States adopted in 1942 the terms niacin to nicotinic acid and niacinamide to nicotinamide to avoid references to nicotine, [12] [13] the terms were incorporated into the United States Adopted Name [14] that was created later in 1961.
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)
Nicotine is readily volatile (vapor pressure 5.5 Pa at 25 °C) [161] On exposure to ultraviolet light or various oxidizing agents, nicotine is converted to nicotine oxide, nicotinic acid (niacin, vitamin B3), and methylamine. [163] Nicotine is chiral and hence optically active, having two enantiomeric forms.
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. [5] [6] It is a water-soluble vitamin. Side effects are minimal.
[109] [110] For example, the enzyme nicotinamidase, which converts nicotinamide to nicotinic acid, is a target for drug design, as this enzyme is absent in humans but present in yeast and bacteria. [43] In bacteriology, NAD, sometimes referred to factor V, is used as a supplement to culture media for some fastidious bacteria. [111]
Large, pharmaceutical doses of the nicotinic acid are used under medical supervision as a treatment for hypercholesterolemia. [3] High doses of nicotinic acid are also associated with a potential for adverse effects , most commonly a niacin flush reaction that is characterized by redness or flushing of the skin, sensations of heat, itching, and ...
Nicotinyl alcohol (pyridylcarbinol) is a niacin derivative used as a hypolipidemic agent and as a vasodilator.It causes flushing and may decrease blood pressure. [2]It appears as a crystal that dissolves in water and alcohol with ease, also soluble in ether; melting range 147–148 °C.
