Regioselectivity in the oxidative deamination of 2-methyl-1,4-diaminobutane catalyzed by diamine oxidases

Diamine oxidase from pea seedlings (PDAO) catalyzes the oxidation of 2-methyl-1,4-diaminobutane in a regioselective fashion, whereas diamine oxidase from pig kidney (KDAO) shows no regioselectivity for the same reaction

Determinazione della Malondialdeide in Gas-Cromatografia con rivelazione a cattura di elettroni

Malondialdehyde, a marker of lipid peroxidation . has been analysed by gas-chromatography with electron capture detection as pentafluorobenzyloxime, after a simple derivatzation step carried out at room temperature . The sensitivity appears similar or higher then those previously reported in HPLC and GC-MS determinations. The described method entails the use of an internal standard, which increase the precision of the overall procedure
