Metabolite Identification

Common Name

ortho-Hydroxyphenylacetic acid

Description

ortho-Hydroxyphenylacetic acid, also known as (o-hydroxyphenyl)acetate or 2-hydroxybenzeneacetic acid, is a member of the class of compounds known as 2(hydroxyphenyl)acetic acids. 2(Hydroxyphenyl)acetic acids are phenylacetic acids that carry a hydroxyl group at the 2-position. ortho-Hydroxyphenylacetic acid is slightly soluble (in water) and a weakly acidic compound (based on its pKa). ortho-Hydroxyphenylacetic acid can be found in a number of food items such as natal plum, lemon verbena, half-highbush blueberry, and parsley, which makes ortho-hydroxyphenylacetic acid a potential biomarker for the consumption of these food products. ortho-Hydroxyphenylacetic acid can be found primarily in blood, feces, and urine. Moreover, ortho-hydroxyphenylacetic acid is found to be associated with phenylketonuria, which is an inborn error of metabolism. ortho-Hydroxyphenylacetic acid is a substrate of the enzyme oxidoreductases (EC 1.14.13.-) in the pathway styrene degradation (KEGG). ortho-Hydroxyphenylacetic acid is also a microbial metabolite.
