| Description | 2-(3,7,11,15,19,23-hexamethyltetracosa-2,6,10,14,18,22-hexaen-1-yl)-3-methyl-1,4-dihydronaphthalene-1,4-dione belongs to the class of organic compounds known as sesterterpenoids. These are terpenes composed of five consecutive isoprene units. 2-(3,7,11,15,19,23-hexamethyltetracosa-2,6,10,14,18,22-hexaen-1-yl)-3-methyl-1,4-dihydronaphthalene-1,4-dione is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Menaquinone 6 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Menaquinone 6 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. |
