Methylmalonic acid (MMA) in serum is an established marker of cobalamin deficiency. MMA and other short-chain dicarboxylic acids react with 1-pyrenyldiazomethane to form stable, highly fluorescent 1-pyrenylmethyl monoesters. We have analyzed these esters in human blood by capillary electrophoresis (CE)
