Metabolite Identification
Common Name3beta-Cucurbita-5,24-dien-3-ol
Description3beta-Cucurbita-5,24-dien-3-ol, also known as euferol, belongs to the class of organic compounds known as cucurbitacins. These are polycyclic compounds containing the tetracyclic cucurbitane nucleus skeleton, 19-(10->9b)-abeo-10alanost-5-ene (also known as 9b-methyl-19-nor lanosta-5-ene), with a variety of oxygenation functionalities at different positions. 3beta-Cucurbita-5,24-dien-3-ol is an extremely weak basic (essentially neutral) compound (based on its pKa).
