Fig. 1: A representative 1H-nuclear magnetic resonance spectrum of a serum sample.
From: Serum metabolite levels identify incipient metastatic progression of rectal cancer
The spectrum was obtained at 800 MHz. Note that the area containing the suppressed water spectra and the glucose region has been omitted. The aryl region from approximately 6.8 ppm to 8.5 ppm is superimposed above. 3HB 3-hydroxybutyrate, Ala alanine, Chol choline, Cit citrate, GPC glycerophosphocholine, Gln glutamine, Glu glutamate, His histidine, Ile isoleucine, Lac lactate, Leu leucine, Lys lysine, Phe phenylalanine, Pro proline, Pyr pyruvate, Trp tryptophan, Tyr tyrosine, Val valine.
