We provide a chemical assignment strategy … We provide a chemical assignment strategy for S-metabolites using 12C- and 13C-based MS and tandem mass spectrometry (MS/MS) spectra recorded by Fourier transform ion cyclotron resonance-mass spectrometry (FTICR-MS) coupled with liquid chromatography (LC) as a case study of the metabolite of onion bulbs. We performed comprehensive peak picking using the theoretical mass difference (1.99579 Da) between 32S-containing monoisotopic ions and their 34S-substituted counterparts for 67 S-containing monoisotopic ions. From these, we identified the specific elemental composition of 22 ions. Finally, we determined that six ions were derived from S-alk(en)ylcysteine sulfoxides and glutathione derivatives. ne sulfoxides and glutathione derivatives.
