Representative chromatogram of m/z 522.3451 in a biological sample (A) and PC (18:1) standard (B) at 11.75 min. Characteristic MS/MS spectra of m/z 522.3451 in a biological sample (C) and PC (18:1(9Z)/0:0) standard (D) at 11.75 min. Fragment interpretation revealed characteristic ions of phosphatidylcholines, such as m/z 104 and 184.
