Metabolite Identification
Common NameMenaquinone 8
DescriptionAC1L1AWW 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. AC1L1AWW 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 8 is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Menaquinone 8 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.
