Fig. 2. Average 850 MHz 1H NMR spectra recorded on aqueous extracts derived from five groups of C2C12 cells. Vertical scales were kept constant in all the 1H spectra. Spectral regions of 0.5–4.5 ppm and 5.2–9.5 ppm are showed, and the water region of 4.5–5.2 ppm was removed. The region of 5.2–9.5 ppm has been magnified 10 times compared to another region of 0.5–4.5 ppm for the purpose of clarity. Identified metabolites are shown in Table 1.
