Metabolite Identification
Common Name2'-Hydroxydaidzein
Description2'-Hydroxydaidzein belongs to the class of organic compounds known as isoflavones. These are polycyclic compounds containing a 2-isoflavene skeleton which bears a ketone group at the C4 carbon atom. Thus, 2'-hydroxydaidzein is considered to be a flavonoid. 2'-Hydroxydaidzein has been detected, but not quantified in, several different foods, such as saffrons (Crocus sativus), celery stalks (Apium graveolens var. dulce), lemon grasses (Cymbopogon citratus), purslanes (Portulaca oleracea), and mugworts (Artemisia vulgaris). This could make 2'-hydroxydaidzein a potential biomarker for the consumption of these foods. 2'-Hydroxydaidzein 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 small amount of articles have been published on 2'-Hydroxydaidzein.
