MS3 data for nystatin P1. The spectrum shows the fragmentation data of the m/z 1088 → 326 ion. The most frequently observed fragmentation corresponds to loss of water: m/z 308 (-1 H20), m/z 290 (-2 H20), m/z 272 (-1 H20). The m/z 146 product ion is consistent with a mycosamine sugar after loss of the hexose (mass difference 180).
