A spectrophotometric method for the determination of borohydride is described. It involves the reduction of NAD’ to a number of isomeric forms of NADH by borohydride. In the standard assay procedure herewith presented, there is a direct proportionality between the absorption at 340 nm and the amount of borohydride in solution over the range IO-100 nmoles, with an effective “molar extinction coe...

This paper describes the investigation of electrocatalytic activity AuCeO2/C catalyst, prepared using microwave irradiation method, towards oxidation sodium borohydride and oxygen reduction reactions in an alkaline medium. It was found that obtained catalyst with Au loading electrochemically active surface area nanoparticles (AuNPs) equal to 71 µg cm−2 0.05 cm2, respectively, showed enhanced in...

N-Acetylneuraminic acid aldolase from Glostridium perfringens was irreversiblv inactivated by 1 mM-bromopyruvate with a half-life of 4.2min at pH 7.2 and 370C. The rate of inactivation was diminished in the presence of pyruvate but not with N-acetyl-D-mannosamine, indicating that the inhibitor acted at, or close to, the pyruvate-binding site. The apparent K, for bromopyruvate, calculated from t...
