Chemical Information
FooDB NameNicotinamide
DescriptionNiacinamide, also known as nicotinamid or nicovit, belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. Niacinamide is a strong basic compound (based on its pKa). Niacinamide exists in all living species, ranging from bacteria to humans. niacinamide and phosphoribosyl pyrophosphate can be converted into nicotinic acid mononucleotide and phosphate through the action of the enzyme nicotinamide phosphoribosyltransferase. In humans, niacinamide is involved in the metabolic disorder called the nad+ signalling pathway (cancer). Niacinamide is an odorless tasting compound. Outside of the human body, Niacinamide is found, on average, in the highest concentration within a few different foods, such as common sages, milk (cow), and cocoa beans and in a lower concentration in common pea and beers. Niacinamide has also been detected, but not quantified in, several different foods, such as pineappple sages, boysenberries, cashew nuts, macadamia nut (m. tetraphylla), and sweet marjorams. This could make niacinamide a potential biomarker for the consumption of these foods. Niacinamide is a potentially toxic compound. A pyridinecarboxamide that is pyridine in which the hydrogen at position 3 is replaced by a carboxamide group.
