Metabolite Identification
Common NameDidymin
DescriptionDidymin belongs to the class of organic compounds known as flavonoid-7-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Didymin is found, on average, in the highest concentration within a few different foods, such as sweet oranges (Citrus sinensis), mandarin orange (clementine, tangerine), and grapefruits (Citrus X paradisi). Didymin has also been detected, but not quantified in, several different foods, such as citrus, teas (Camellia sinensis), red tea, green tea, and grapefruit/pummelo hybrids (Citrus paradisi X Citrus maxima). This could make didymin a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Didymin.
