Metabolite Identification
Common NameEremopetasitenin A2
DescriptionEremopetasitenin A2 belongs to the class of organic compounds known as naphthofurans. Naphthofurans are compounds containing a furan ring fused to a naphthalene moiety. Furan is a 5 membered- ring aromatic ring with four carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon made up of two fused benzene rings. Eremopetasitenin A2 is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, eremopetasitenin A2 has been detected, but not quantified in, green vegetables. This could make eremopetasitenin A2 a potential biomarker for the consumption of these foods.
