Niacin, also known as vitamin B3 or nicotinic acid, is an organic compound with the formula C5H4NCO2H. This colourless, 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 Other forms of vitamin B3 include the corresponding amide, nicotinamide (“niacinamide”), where the carboxyl group has been replaced by a carboxamide group (CONH2), as well as more complex amides and a variety of esters. The terms niacin, nicotinamide, and vitamin B3 are often used interchangeably to refer to any member of this family of compounds, since they have the same biochemical activity.
Vitamin B3, or niacin, works with other b-complex vitamins to metabolize food and provide energy for the body. Niacin was first discovered by researchers looking for a link between diet and the disease pellagra. They determined that pellagra was common among people with a corn-based diet, and they were able to treat the disease with nicotinic acid, a form of niacin.
The body uses the water-soluble vitamin B3 in the process of releasing energy from carbohydrates. It is needed to form fat from carbohydrates and to process alcohol.
