Abstract
In the present 2.1 T15N NMR study two different kinds of experiments are presented. In one we show that metabolic reactions of 15N-labelled glycine can be followed in the isolated rat liver. In the second we demonstrate that [15N]glycine can be detected using NMR in vivo. For quantification and identification of glycine and metabolites 15N-isotope analysis (emission spectrometry technique) was used. To our knowledge, this is the first demonstration of 15N NMR for study of the metabolism of 15N-labelled compounds in vivo.
