Chemical Information
FooDB Name2-Hydroxyphenylacetic acid
Descriptionortho-Hydroxyphenylacetic acid, also known as (O-hydroxyphenyl)acetate or 2-hydroxybenzeneacetic acid, belongs to the class of organic compounds known as 2(hydroxyphenyl)acetic acids. These are phenylacetic acids that carry a hydroxyl group at the 2-position. ortho-Hydroxyphenylacetic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). ortho-Hydroxyphenylacetic acid exists in all living organisms, ranging from bacteria to humans. ortho-Hydroxyphenylacetic acid has been detected, but not quantified in, several different foods, such as orange mints, chanterelles, cascade huckleberries, garden tomato (var.), and common grapes. This could make ortho-hydroxyphenylacetic acid a potential biomarker for the consumption of these foods. ortho-Hydroxyphenylacetic acid, with regard to humans, has been found to be associated with several diseases such as eosinophilic esophagitis and irritable bowel syndrome; ortho-hydroxyphenylacetic acid has also been linked to the inborn metabolic disorder phenylketonuria.
