Metabolite Identification
Common Name4-Hydroxyphenylacetaldehyde
Description4-Hydroxyphenylacetaldehyde, also known as POH-PH-CH2CHO, belongs to the class of organic compounds known as phenylacetaldehydes. Phenylacetaldehydes are compounds containing a phenylacetaldehyde moiety, which consists of a phenyl group substituted at the second position by an acetalydehyde. 4-Hydroxyphenylacetaldehyde exists in all living species, ranging from bacteria to plants to humans. 4-Hydroxyphenylacetaldehyde has been detected, but not quantified in, several different foods, such as plains prickly pears (Opuntia macrorhiza), dills (Anethum graveolens), half-highbush blueberries (Vaccinium angustifolium X Vaccinium corymbosum), cloves (Syzygium aromaticum), and wild carrots (Daucus carota). This could make 4-hydroxyphenylacetaldehyde a potential biomarker for the consumption of these foods. 4-Hydroxyphenylacetaldehyde is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on 4-Hydroxyphenylacetaldehyde.
