| Common Name | 4-Methoxycinnamic acid |
|---|
| Description | 4-Methoxycinnamic acid, also known as para-methoxycinnamate or O-methyl-p-coumarate, belongs to the class of organic compounds known as cinnamic acids. These are organic aromatic compounds containing a benzene and a carboxylic acid group forming 3-phenylprop-2-enoic acid. Outside of the human body, 4-Methoxycinnamic acid is found, on average, in the highest concentration within turmerics. 4-Methoxycinnamic acid has also been detected, but not quantified in cow milk and wild celeries. This could make 4-methoxycinnamic acid a potential biomarker for the consumption of these foods. |
