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

Glutamine is an essential fuel for tissues with high rates of cell replication, such as enterocytes and lymphocytes. Infusion of 13C-labeled glutamine tracers allows for measurement of the rates of production, utilization and oxidation of glutamineÏs carbon skeleton in vivo. The use of this tracer,
We report a method for determining plasma und urinary [(15)N]urea enrichments in an abundance range between 0.37 and 0.52 (15)N atom% (0-0.15 atom% excess (APE) (15)N) using a dimethylaminomethylene derivative. Compared with conventional off-line preparation and (15)N analysis of urea, this method r
