Abstract: Methylmalonic acid (MMA) is a very short dicarboxylic acid (methylpropanedioic acid; CH3CH(COOH)2; pKa1, 3.07; pKa2, 5.76) associated with vitamin B12 deficiency and many other patho-physiological conditions. In this work, we investigated several carboxylic groups-specific derivatization… read more here.
