Common NameGlabranin
DescriptionGlabranin belongs to the class of organic compounds known as annonaceous acetogenins. These are waxy derivatives of fatty acids (usually C32 or C34), containing a terminal carboxylic acid combined with a 2-propanol unit at the C-2 position to form a methyl- substituted alpha,beta-unsaturated-gamma-lactone. One of their interesting structural features is a single, adjacent, or nonadjacent tetrahydrofuran (THF) or tetrahydropyran (THP) system with one or two flanking hydroxyl group(s) at the center of a long hydrocarbon chain. Glabranin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, Glabranin has been detected, but not quantified in, a few different foods, such as alcoholic beverages, fruits, and sugar apples. Glabranin is found in Annona glabra , Annona glauca , Glycyrrhiza glabra , Glycyrrhiza lepidota , Glycyrrhiza uralensis, Helichrysum forskahlii , Piscidia erythrina, Piscidia piscipula and Sophora tomentosa. It was first documented in 2000 (PMID: 11413487). This could make glabranin a potential biomarker for the consumption of these foods (PMID: 16902246) (PMID: 17374880) (PMID: 20044567).
