Metabolite Identification
Common NamePhenoxyacetic acid
DescriptionPhenoxyacetic acid, also known as phenoxyacetate or POA, belongs to the class of organic compounds known as phenoxyacetic acid derivatives. Phenoxyacetic acid derivatives are compounds containing an anisole where the methane group is linked to an acetic acid or a derivative. Phenoxyacetic acid exists as a solid, slightly soluble (in water), and a weakly acidic compound (based on its pKa). Within the cell, phenoxyacetic acid is primarily located in the cytoplasm. In humans, phenoxyacetic acid is involved in the rosiglitazone metabolism pathway. Phenoxyacetic acid is a sweet and sour tasting compound that can be found in cocoa and cocoa products. This makes phenoxyacetic acid a potential biomarker for the consumption of this food product.
