Identification
Common NameCucurbitacin K
ClassSmall Molecule
DescriptionCucurbitacin k is a member of the class of compounds known as cucurbitacins. Cucurbitacins 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. Cucurbitacin k can be found in bitter gourd, which makes cucurbitacin k a potential biomarker for the consumption of this food product.
