The effects of methyl rotation on electron spin-lattice relaxation times were examined by pulsed electron paramagnetic resonance for the major radicals in gamma-irradiated polycrystalline alpha-amino isobutyric acid, dimethyl-malonic acid, and L-valine. The dominant radical is the same in irradiated dimethyl-malonic

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)
