Representative spectra of branched-chain amino acids (leucine, isoleucine, and valine); (a), 2-oxoisovalerate (b) and acetone (c) of culture media consisting of DMEM supplemented with 10% FBS before (black) or after incubation of glioma (blue), glioblastoma (green), and neuroblastoma (red) cells for 24 h obtained by 1H-NMR spectroscopy. The ranges of chemical shifts (δ) with peaks for all three BCAAs (a); 2- oxoisovalerate (b) and acetone (c) are depicted.
