Metabolite Identification
Common NameEthyl gallate
DescriptionEthyl gallate, also known as E313 or ethyl gallic acid, belongs to the class of organic compounds known as galloyl esters. These are organic compounds that contain an ester derivative of 3,4,5-trihydroxybenzoic acid. Ethyl gallate exists as a solid, slightly soluble (in water), and a very weakly acidic compound (based on its pKa). Ethyl gallate has been primarily detected in urine. Within the cell, ethyl gallate is primarily located in the cytoplasm. Outside of the human body, ethyl gallate can be found in fruits, grape wine, guava, and vinegar. This makes ethyl gallate a potential biomarker for the consumption of these food products.
