Series of liquid-state 13C spectra recorded in a 600-MHz spectrometer on a 80 mM hyperpolarized [1-13C]pyruvate sample (pH 7.2) inside a 5-mm MR tube. Acquisition was initiated 26 s after dissolution and the repetition time was set to 3.3 s with a flip angle of 10°. The two most intense peaks at 173 ppm and 181.6 ppm correspond to [1-13C]pyruvate and [1-13C]pyruvate hydrate, respectively. The natural abundance [2-13C]pyruvate and [2-13C]pyruvate hydrate were also observed at 207.8 ppm and 96.5 ppm, respectively.
