Metabolism of Glycine-2-C14 in Man: V. Further Considerations of Pulmonary Excretion of C14O2.

Abstract

The 47th component of pulmonary excretion after intravenous injection of glycine-2-C14 was determined and found to have an average half time of 71.5 days. Recalculation of the half time and associated C14 excretion showed that decreasing component I had an average half time of 0.12 day and that 20.8% of the C14 was excreted with this rate process. For the others the half times and percentages were 0.97 day, 14.2%; 6.1 days, 25.6%, and 71.5 days, 25.7%.
