Metabolite Identification
Common NameIsobergapten
DescriptionIsobergapten is a member of the class of compounds known as angular furanocoumarins. Angular furanocoumarins are furanocoumarins, with a structure characterized by a furan ring angularly fused to a coumarin. Isobergapten is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Isobergapten can be found in parsnip, which makes isobergapten a potential biomarker for the consumption of this food product. Isobergapten is a non-carcinogenic (not listed by IARC) potentially toxic compound. Furocoumarin toxins can cause stomach ache and may also cause a painful skin reaction when contact with the parsnip plant is combined with UV rays from sunlight (L579) (T3DB).
