Metabolite Identification
Common NameVitamin E Nicotinate
Description2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-3,4-dihydro-2H-1-benzopyran-6-yl pyridine-3-carboxylate belongs to the class of organic compounds known as vitamin e compounds. These are a group of fat-soluble compounds containing or derived either from a tocopherol or a tocotrienol skeleton. Based on a literature review very few articles have been published on 2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-3,4-dihydro-2H-1-benzopyran-6-yl pyridine-3-carboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Vitamin e nicotinate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Vitamin E 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.
