These metabolic fates were estimated by drawing a complete balance of the nitrogens and of the carbon chains of the extracted glutamine and studying the formation of 14CO2 from 14C-glutamine. It was found that glucose production constitutes the major fate for glutamine metabolism with 1 mM glutamine and that glutamine oxidation constitutes less than 20% of the metabolic fate of the carbon skeleton of this amino acid. With 5 or 10 mM glutamine however, the maximal oxidation to CO2 becomes more important (25%).Read More
