2-octaprenylphenol
2-[(2e,6e,10e,14e,18e,22e,26e)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaenyl]phenol, also known as 2-all-trans-octaprenylphenol, is a member of the class of compounds known as polyprenylphenols. Polyprenylphenols are compounds containing a polyisoprene chain attached to a phenol group. 2-[(2e,6e,10e,14e,18e,22e,26e)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaenyl]phenol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 2-[(2e,6e,10e,14e,18e,22e,26e)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaenyl]phenol can be found in a number of food items such as lettuce, pak choy, common verbena, and tree fern, which makes 2-[(2e,6e,10e,14e,18e,22e,26e)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaenyl]phenol a potential biomarker for the consumption of these food products. 2-[(2e,6e,10e,14e,18e,22e,26e)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaenyl]phenol may be a unique E.coli metabolite.
2-Octaprenylphenol
