Metabolite Identification
Common Nametrans-Grandmarin isovalerate
Descriptiontrans-Grandmarin isovalerate belongs to the class of organic compounds known as angular pyranocoumarins. These are organic compounds containing a pyran (or a hydrogenated derivative) angularly fused to a coumarin moiety. trans-Grandmarin isovalerate has been detected, but not quantified in, citrus. This could make trans-grandmarin isovalerate a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on trans-Grandmarin isovalerate.
