Figure 5

The comparison of observed mass spectra and the calculated isotope pattern. The graphs showing mass spectra from m/z 834 to 837, m/z 856 to 859, and m/z 872 to 875 (black lines). The red lines indicated the calculated isotope patterns of [PS(39:0) + H]⁺, [PI(34:0) + NH4]⁺ and [PS(39:0) + K]⁺.
