Gas chromatography mass spectrometry has been used to determine the 15N enrichment of plasma glycine of rabbits at various times following the intravenous administration of 15N-glycine. These data were used to prepare isotope enrichment time decay curves for eleven individual animals. The slopes and intercepts of least squares lines that describe the decay curves were considerably more accurately than those reported in similar studies employing radioactive tracers. Individual glycine pool sizes (13.8-37.4 micronmoles per 100 g body wt), turnovers rates (2.66-3.36 pools h-1) and flux (50.4-99.7 micronmoles h-1 per 100 g body wt) were estimated from these parameters in a group of animals and compared with the literature values. These results demonstrate that low risk non-radioactive stable isotopes can be substituted for radioactive tracers in studies of human amino acid metabolism, with considerable saving in time and without loss in accuracy, when gas chromatography mass spectrometry is used to determine plasma amino acid and stable isotope enrichment.
