Metabolite Identification
Common NameLepalone
DescriptionLepalone belongs to the class of organic compounds known as alpha-branched alpha,beta-unsaturated ketones. These are alpha,beta-unsaturated ketones that carry a branch on the alpha carbon. They have the generic structure RC(=O)C(R')=C, R = organyl group and R'= any heteroatom. Lepalone has been detected, but not quantified in, herbs and spices and roman camomiles (Chamaemelum nobile). This could make lepalone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Lepalone.
