Metabolic pathways interrogated according to 13C labelled position, blue C2 position, red C1 position. (A) [1-13C]pyruvate spectrum showing conversion to lactate, pyruvate hydrate, alanine and bicarbonate and (B) Example spectra acquired in the first 60s following [2-13C]pyruvate infusion in the in vivo rat heart. [2-13C]pyruvate is observed at 207.8 ppm. Peaks from (1) [5-13C]glutamate, (2) [1-13C]citrate, (3) [1-13C]acetylcarnitine, (4) [1-13C]pyruvate, (5) [2-13C]lactate & (6) [2-13C]alanine can be seen.
