Figure 7

UV-TriPA hyperpolarised [U-13C,d7]glucose conversion in live prostate carcinoma cells (PC-3). A build-up of the glycolysis derived metabolite lactate could be followed over 30 s. Intermediates in glycolysis are identified by 13C-13C coupling constants due to the uniformly labelled substrate and indicated by black bars in a sum of 30 spectra: Lactate (LAC), Glutamate carbon #1 and #5 (GLU-C1 and C5), 3-phophoglucerate (3PG), unspecified amino acid (AA). Remaining radical precursor is identified outside ppm area of interest as singlets (TriPA). The signal denoted * is likely to originate from the precursor.
