Metabolite Identification
Common NameGlycyrol
DescriptionGlycyrol, also known as neoglycyrol, belongs to the class of organic compounds known as coumestans. These are polycyclic aromatic compounds containing a coumestan moiety, which consists of a benzoxole fused to a chromen-2-one to form 1-Benzoxolo[3,2-c]chromen-6-one. They are oxidation products of pterocarpan. Glycyrol is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, glycyrol has been detected, but not quantified in, root vegetables. This could make glycyrol a potential biomarker for the consumption of these foods.
