| Common Name | m-Tyramine |
|---|
| Description | m-Tyramine belongs to the class of organic compounds known as phenethylamines. Phenethylamines are compounds containing a phenethylamine moiety, which consists of a phenyl group substituted at the second position by an ethan-1-amine. m-Tyramine has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make m-tyramine a potential biomarker for the consumption of these foods. m-Tyramine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on m-Tyramine. |
