| Description | (2R)-2,5,7,8-Tetramethyl-2-(4,8,12-trimethyltrideca-3,7,11-trienyl)-3,4-dihydrochromen-6-ol, also known as tocotrienol, a or alpha-tocotrienol, belongs to the class of organic compounds known as tocotrienols. These are vitamin E derivatives containing an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocopherols that contain a saturated trimethyltridecyl chain. Based on a literature review very few articles have been published on (2R)-2,5,7,8-Tetramethyl-2-(4,8,12-trimethyltrideca-3,7,11-trienyl)-3,4-dihydrochromen-6-ol. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2r)-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltrideca-3,7,11-trienyl)-3,4-dihydrochromen-6-ol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2R)-2,5,7,8-Tetramethyl-2-(4,8,12-trimethyltrideca-3,7,11-trienyl)-3,4-dihydrochromen-6-ol 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. |
