From: Urinary metabolomic signature of esophageal cancer and Barrett’s esophagus
Representative urine 1H-NMR spectrum of esophageal cancer. Urinary 1H-NMR spectrum of esophageal cancer. X-axis = chemical shift relative to internal standard, DSS-d6, Y-axis = peak amplitude relative to DSS-d6. A) Full 1H-NMR spectrum. B) Representative region of spectrum with labeled metabolites. Black line represents 1H-NMR spectrum, blue line represents compound signature corresponding to 2-aminobutyrate, red line represents compound signature corresponding to pantothenate. DSS-d6, sodium 2,2-dimethyl-2-silapentane-5-sulfonate-d6.
