niacin,  vit B3

Niacin (also known as vitamin B₃, nicotinic acid, or less commonly vitamin PP; archaic terms include pellagra-preventive and anti-dermatitis factor) is an organic compound with the formula C
6H
5NO
2 and, depending on the definition used, one of the 40 to 80 essential human nutrients.

Niacin is one of five vitamins (when lacking in human diet) associated with a pandemic deficiency disease: niacin deficiency (pellagra), vitamin C deficiency (scurvy), thiamin deficiency (beriberi), vitamin D deficiency (rickets and osteomalacia), vitamin A deficiency (night blindness and other symptoms). Niacin has been used for over 50 years to increase levels of HDL in the blood and has been found to decrease the risk of cardiovascular events modestly in a number of controlled human trials.^[3]

This colorless, water-soluble solid is a derivative of pyridine, with a carboxyl group (COOH) at the 3-position. Other forms of vitamin B₃ include the corresponding amide, nicotinamide (“niacinamide”), where the carboxyl group has been replaced by a carboxamide group (CONH
2), as well as more complex amides and a variety of esters. Nicotinic acid and niacinamide are convertible to each other with steady world demand rising from 8500 tonnes per year in 1980s to 40,000 in recent years.^[4]

Niacin cannot be directly converted to nicotinamide, but both compounds could be converted to and are precursors of NAD andNADP in vivo.^[5] Nicotinic acid, nicotinamide, and tryptophan (via quinoline acid) are co-factors for nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). NAD converts to NADP by phosphorylation in the presence of the enzyme NAD+ kinase. NADP and NAD are coenzyme for many dehydrogenases, participating in many hydrogen transfer processes.^[6] NAD is important in catabolism of fat, carbohydrate, protein, and alcohol, as well as cell signaling and DNA repair, and NADP mostly in anabolism reactions such as fatty acid and cholesterol synthesis.^[6] High energy requirements (brain) or high turnover rate (gut, skin) organs are usually the most susceptible to their deficiency.^[7]

Although the two are identical in their vitamin activity, nicotinamide does not have the same pharmacological effects (lipid modifying effects) as niacin. Nicotinamide does not reduce cholesterol or cause flushing.^[8] Nicotinamide may be toxic to the liver at doses exceeding 3 g/day for adults.^[9] Niacin is involved in both DNA repair, and the production of steroid hormones in theadrenal gland.
