(2R,3S)-2-methylisocitrate

(1R,2S)-1-Hydroxy-1-methylpropane-1,2,3-tricarboxylic acid

C7H7O7 (203.0192)


(2r,3s)-2-methylisocitrate, also known as methylisocitric acid or (2s,3r)-3-hydroxybutane-1,2,3-tricarboxylate, belongs to tricarboxylic acids and derivatives class of compounds. Those are carboxylic acids containing exactly three carboxyl groups (2r,3s)-2-methylisocitrate is soluble (in water) and a weakly acidic compound (based on its pKa). (2r,3s)-2-methylisocitrate can be found in a number of food items such as green zucchini, cinnamon, fig, and nanking cherry, which makes (2r,3s)-2-methylisocitrate a potential biomarker for the consumption of these food products.
