Common NameInositol nicotinate
Descriptioninositol hexanicotinate, also known as hexanicotinoyl inositol or inositol niacinic acid, belongs to the class of organic compounds known as hexacarboxylic acids and derivatives. These are carboxylic acids containing exactly six carboxyl groups. inositol hexanicotinate is a strong basic compound (based on its pKa). Patients with alcoholism typically experience increased intestinal permeability, leading to negative health outcomes.Hartnup disease is a hereditary nutritional disorder resulting in niacin deficiency. This compound has been identified in human blood as reported by (PMID: 31557052 ). Inositol nicotinate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Inositol nicotinate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
