From: Identification of unique cardiolipin and monolysocardiolipin species in Acinetobacter baumannii
Fragmentation patterns of monolysocardiolipin and cardiolipins. PSD analysis of the peaks at m/z 1183.3 (a) 1293.0 (b), 1403.9 (c) and 1165.6 (d). (a) PSD analysis of the peak at m/z 1183.3: ion fragments correspond to PA (m/z 618.9), PA (m/z 562.9), LPA-H2O (m/z 390.7) and the fatty acid 16:0 (m/z 254.6). (b) PSD analysis of the peak at m/z 1293.0: ion fragments correspond to PGP-H2O (m/z 808.9), PA (m/z 673.2), PA (m/z 563.0), LPA (m/z 408.9), LPA-H2O (m/z 391.1) and fatty acids 18:1 (m/z 281.4) and 16:0 (m/z 254.6). (c) PSD analysis of the peak at m/z 1403.9: ion fragments correspond to PGP-H2O (m/z 809.9), PG-H2O (m/z 729.4), PA (m/z 673.6), LPA (m/z 408.9), LPA-H2O (m/z 391.1). In the x-axis enlargement of m/z range 150–350, two peaks are referable to the fatty acids 18:1 (m/z 281.4) and 16:0 (m/z 254.5). (d) PSD analysis of the peak at m/z 1165.6: ion fragments correspond to PGP-H2O (m/z 809.5), PG (m/z 747.4), PGP-H2O (m/z 729.6), PA (m/z 673.7), LPA (m/z 436.3), LPA-H2O (m/z 391.8). In the x-axis enlargement of m/z range 150–350, two peaks are referable to fatty acids 18:1 (m/z 281.5) and 16:0 (m/z 255.4).
