Figure 1From: Metabolite profiling of human colon carcinoma – deregulation of TCA cycle and amino acid turnoverRepresentative GC-TOF chromatograms of paired colon carcinoma (thin line) and normal tissue (bold line) at extracted ions m/z 218+100 between 530–610 s. Select mass spectra (m/z 80–300) are given for the significantly different metabolites cysteine and phenylalanine, and the non-altered compound creatinine.Back to article page
