The 13C mass isotopomer distribution of liver phosphoenolpyruvate (PEP) yields important information on the regulation of gluconeogenesis and the citric acid cycle. A convenient technique is presented for measuring the mass isotopomer distribution of PEP in tissue extracts. The procedure involves re

We present gas chromatographic-mass spectrometric assays for (i) the concentration of sulfamethoxazole and (ii) the concentration and molar percentage enrichment of acetyl-sulfamethoxazole in biological fluids. The compounds are extracted with ethyl acetate, derivatized with either diazomethane or p

We present two techniques for determining the concentration and \({ }^{13} \mathrm{C}\) enrichment of acetate in biological fluids. After the sample has been spiked with an internal standard of \(\left[2,2,2,{ }^{2} \mathrm{H}_{3}, 1-{ }^{13} \mathrm{C}\right]\) acetate, acetate is first enzymatical
