Common NameMenaquinone-9
Description2-methyl-3-(3,7,11,15,19,23,27,31,35-nonamethylhexatriaconta-2,6,10,14,18,22,26,30,34-nonaen-1-yl)-1,4-dihydronaphthalene-1,4-dione belongs to the class of organic compounds known as vitamin k compounds. These are quinone lipids containing a methylated naphthoquinone ring structure, and vary in the aliphatic side chain attached at the 3-position. 2-methyl-3-(3,7,11,15,19,23,27,31,35-nonamethylhexatriaconta-2,6,10,14,18,22,26,30,34-nonaen-1-yl)-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-9 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Menaquinone-9 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.
