We present gas chromatographic/mass spectrometric and gas chromatographic/isotope ratio mass spectrometric assays of the 13C enrichment of plasma urea converted to its dimethylaminomethylene derivative. The limits of sensitivity of the two techniques are 0.2% and 0.02%, respectively. The techniques

We developed gas chromatography-mass spectrometry assays for the concentration and mass isotopomer distribution of malonyl-CoA in tissues. The assay involves perchloric acid extraction of the tissue, spiking the extract with [U-13 C 3 ]malonyl-CoA or dimethylmalonyl-CoA internal standard, isolation
We developed gas chromatography-mass spectrometry assays for the concentration and mass isotopomer distribution of propionyl-CoA, methylmalonyl-CoA, and succinyl-CoA in tissues. The assays involves perchloric acid extraction of the tissue, spiking the extract with [ 2 H 5 ]propionyl-CoA and [ 2 H 4
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
A method was developed for measuring protein fractional synthetic rates using the N-methoxycarbonylmethyl ester (MCM) derivative of L-[ 1-13C ] valine and on-line gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS). The derivatization procedure can be performed rapidly and GC s
