Natural Product Identification
Common NameRetrocalamin
DescriptionRetrocalamin belongs to the class of organic compounds known as naphthopyrans. Naphthopyrans are compounds containing a pyran ring fused to a naphthalene moiety. Furan is a 6 membered-ring non-aromatic ring with five carbon and one oxygen atoms. Naphthalene is a polycyclic aromatic hydrocarbon made up of two fused benzene rings. Retrocalamin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, retrocalamin has been detected, but not quantified in, citrus and mandarin orange (clementine, tangerine). Retrocalamin is found in Skimmia japonica. This could make retrocalamin a potential biomarker for the consumption of these foods.
