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 present the analysis of the stable carbon isotope compositions of 14 individual N-pivaloyl-isopropyl (NPP) amino acid esters by gas chromatography-combustion isotope ratio mass spectrometry (GC-C-IRMS). The mean reproducibility of derivatization procedure and GC-C-IRMS analysis was 0.45โฐ (ra
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
