   浓缩The active concentration of trivalent arsenic

实验过程

The procedure used was the same as for N-(3-(4-arsenosophenylcarbamoylmethylthio)propanoyl)-L-glutamic acid, using 3.00 mL (210 μmol) of 70.0 mM BRAO in DMSO, the disulfide of disodium N-(3-mercaptopropanoyl)-D-glucosamine (0.67 g), 0.5 M bicarbonate buffer, pH 9 (11.96 mL, 6.0 mmol), and 0.69 M triphenylphosphine in DMSO (1.9 mL, 1.3 mmol). The active concentration of trivalent arsenic was found to be 13.5 mM (11.0 mL of solution).
