Metabolite Identification
Common Namep-Hydroxyphenylacetic acid
Descriptionp-Hydroxyphenylacetic acid, also known as 4-hydroxybenzeneacetate or 4-carboxymethylphenol, belongs to the class of organic compounds known as 1-hydroxy-2-unsubstituted benzenoids. These are phenols that are unsubstituted at the 2-position. p-Hydroxyphenylacetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). p-Hydroxyphenylacetic acid exists in all living species, ranging from bacteria to humans. p-hydroxyphenylacetic acid can be biosynthesized from homovanillin; which is catalyzed by the enzyme aldehyde dehydrogenase, dimeric nadp-preferring. A monocarboxylic acid that is acetic acid in which one of the methyl hydrogens is substituted by a 4-hydroxyphenyl group. In humans, p-hydroxyphenylacetic acid is involved in the metabolic disorder called tyrosinemia type I. Outside of the human body, p-Hydroxyphenylacetic acid is found, on average, in the highest concentration within a few different foods, such as olives, american cranberries, and grape wines and in a lower concentration in corns, beers, and oats. p-Hydroxyphenylacetic acid has also been detected, but not quantified in, several different foods, such as common wheats, herbs and spices, cocoa beans, dandelions, and evening primroses. This could make p-hydroxyphenylacetic acid a potential biomarker for the consumption of these foods. p-Hydroxyphenylacetic acid is a potentially toxic compound. p-Hydroxyphenylacetic acid, with regard to humans, has been found to be associated with several diseases such as colorectal cancer, perillyl alcohol administration for cancer treatment, crohn's disease, and ulcerative colitis; p-hydroxyphenylacetic acid has also been linked to the inborn metabolic disorder phenylketonuria.
