Metabolite Identification
Common Name(S)-2,3-Dihydro-7-hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid
Description(S)-2,3-Dihydro-7-hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid, also known as 2-(7-hydroxy-2-methyl-4-oxo-3,4-dihydro-2H-1-benzopyran-5-yl)acetate, belongs to the class of organic compounds known as chromones. Chromones are compounds containing a benzopyran-4-one moiety (S)-2,3-Dihydro-7-hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid has been detected, but not quantified in, green vegetables. This could make (S)-2,3-dihydro-7-hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on (S)-2,3-Dihydro-7-hydroxy-2-methyl-4-oxo-4H-1-benzopyran-5-acetic acid.
