Metabolite Identification
Common NameDopamine quinone
DescriptionDopamine quinone, also known as DoQ, belongs to the class of organic compounds known as o-benzoquinones. These are benzoquinones where the two C=O groups are attached at the 1- and 2-positions, respectively. Dopamine quinone has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make dopamine quinone a potential biomarker for the consumption of these foods. Dopamine quinone 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 Dopamine quinone.
