Metabolite Identification
Common Name4-[2-[5,5-Dimethyl-8-(4-methylphenyl)-6H-naphthalen-2-yl]ethynyl]benzoic acid
Description4-{2-[5,5-dimethyl-8-(4-methylphenyl)-5,6-dihydronaphthalen-2-yl]ethynyl}benzoic acid belongs to the class of organic compounds known as sesquiterpenoids. These are terpenes with three consecutive isoprene units. Based on a literature review very few articles have been published on 4-{2-[5,5-dimethyl-8-(4-methylphenyl)-5,6-dihydronaphthalen-2-yl]ethynyl}benzoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-[2-[5,5-dimethyl-8-(4-methylphenyl)-6h-naphthalen-2-yl]ethynyl]benzoic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-[2-[5,5-Dimethyl-8-(4-methylphenyl)-6H-naphthalen-2-yl]ethynyl]benzoic acid 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.
