Abstract

The metabolic fate of 13C1-labeled butyrate in the liver of living rats has been studied by 13C NMR. The formation of the ketone bodies acetoacetate and beta-hydroxybutyrate was observed in vivo as well as resonances from glutamate, glutamine, and carbonate. The observed time course of these metabolites demonstrates the potential of the technique to measure enzyme kinetics in vivo and also to measure the enzyme capacity of a given organ to metabolize a substrate. The in vivo spectra were compared to in vitro spectra of the excised liver and perchloric acid extracts of the liver. Observation of the metabolites and monitoring of their time course in vivo would not have been possible without distinct improvements in the spectral resolution and the spatial localization of the radio-frequency field within the liver. As a novel approach, we have selected the carbonyl region of the 13C NMR spectra for identifying the ketone bodies and other oxidation products in the liver.
