| Common Name | 3,7-Dimethylquercetin |
|---|
| Description | 3,7-Dimethylquercetin belongs to the class of organic compounds known as 7-o-methylated flavonoids. These are flavonoids with methoxy groups attached to the C7 atom of the flavonoid backbone. Thus, 3,7-dimethylquercetin is considered to be a flavonoid. 3,7-Dimethylquercetin exists in all living organisms, ranging from bacteria to humans. 3,7-Dimethylquercetin is found, on average, in the highest concentration within grape wine and beer. This could make 3,7-dimethylquercetin a potential biomarker for the consumption of these foods. 3,7-Dimethylquercetin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a small amount of articles have been published on 3,7-Dimethylquercetin. |
