Figure 10. Mass spectrometry analysis of the sugars extracted from GP candidates by acid hydrolysis.

Figure 10

The sugars were analyzed by LC-MS/MS. In each panel, the molecular structure of the expected sugar is shown above the MS/MS spectrum, with the expected fragmentation pattern and associated mass loss. The MS/MS spectra are annotated with the total mass loss intervals and with mass loss combinations that lead to the size of the observed peaks. All spectra are shown as sodium adducts. Panel A: Pse5Am7Ac. Panel B: Pse5Ac7Ac. Panel C: Leg5AmNMe7Ac. Panel D: Bac2Ac.
