Message definition (Niacin)
Niacin as a chemical compound was first described by chemist [[Hugo Weidel]] in 1873 in his studies of [[nicotine]], but that predated by many years the concept of food components other than protein, fat and carbohydrates that were essential for life. Vitamin nomenclature was initially alphabetical, with [[Elmer McCollum]] calling these fat-soluble A and water-soluble B. Over time, eight chemically distinct, water-soluble B vitamins were isolated and numbered, with niacin as vitamin B<sub>3</sub>.
