4-o-methylglucuronic acid belongs to glucuronic acid derivatives class of compounds. Those are compounds containing a glucuronic acid moiety (or a derivative), which consists of a glucose moiety with the C6 carbon oxidized to a carboxylic acid. 4-o-methylglucuronic acid is soluble (in water) and a weakly acidic compound (based on its pKa). 4-o-methylglucuronic acid can be found in cashew nut and european plum, which makes 4-o-methylglucuronic acid a potential biomarker for the consumption of these food products.
