Natural Product Identification
Common Name3,4-Dihydroxymandelic acid
Description3,4-Dihydroxymandelic acid, also known as DOMA or 3,4-dihydroxyphenylglycolate, belongs to the class of organic compounds known as catechols. Catechols are compounds containing a 1,2-benzenediol moiety. 3,4-Dihydroxymandelic acid exists in all living organisms, ranging from bacteria to humans. Within humans, 3,4-dihydroxymandelic acid participates in a number of enzymatic reactions. In particular, 3,4-dihydroxymandelic acid can be biosynthesized from 3,4-dihydroxymandelaldehyde through its interaction with the enzyme aldehyde dehydrogenase, dimeric nadp-preferring. In addition, 3,4-dihydroxymandelic acid and guaiacol can be converted into vanillylmandelic acid and pyrocatechol through the action of the enzyme catechol O-methyltransferase. In humans, 3,4-dihydroxymandelic acid is involved in the metabolic disorder called tyrosinemia type I. Outside of the human body, 3,4-Dihydroxymandelic acid has been detected, but not quantified in several different foods, such as yellow wax beans, soy beans, pomegranates, cucurbita (gourd), and daikon radish.
