| Common Name | Pyranomammea C | 
|---|
| Description | Pyranomammea C belongs to the class of organic compounds known as linear pyranocoumarins. These are organic compounds containing a pyran (or a hydrogenated derivative) linearly fused to a coumarin moiety. Pyranomammea C has been detected, but not quantified in, fruits. This could make pyranomammea C a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Pyranomammea C. |
