Quantitation rates of substrate oxidation in vivo using stable isotope tracing

Rates of 13C-glucose oxidation in vivo using stable isotope tracing. C57Bl/6 mice either fasted or were given free access to food for 4 hours prior to administration of 2.5 mg 13C-glucose. Plotted in R & ggplot2. Performed in the Promethion indirect calorimeter.
