| Description | 2-Hydroxy-4-methoxy-3-(3-methyl-2-butenyl)-6-(2-phenylethenyl)benzoic acid, also known as 3-hydroxy-4-prenyl-5-methoxystilbene-2-carboxylic acid or cajaninstilbene acid, belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. 2-Hydroxy-4-methoxy-3-(3-methyl-2-butenyl)-6-(2-phenylethenyl)benzoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 2-Hydroxy-4-methoxy-3-(3-methyl-2-butenyl)-6-(2-phenylethenyl)benzoic acid has been detected, but not quantified in, pulses. Cajaninstilbene acid is found in Cajanus cajan . This could make 2-hydroxy-4-methoxy-3-(3-methyl-2-butenyl)-6-(2-phenylethenyl)benzoic acid a potential biomarker for the consumption of these foods. |
