    The diacylglycerols (DG) molecular species and their fatty acid (FA) composition were investigated by electrospray mass spectrometry (ESI-MS) and by gas chromatography with flame ionisation detection (GC-FID) in haemolymph of Locusta migratoria after application of adipokinetic hormones (AKH). The analyses showed (1) a heterogeneous distribution of individual DGs in haemolymph after the AKH application. The results revealed that mobilization of the DGs is specific and that palmitic (C16:0) and oleic acid (C18:1) residues form about 20% of the total mobilized DGs. (2) Analysis of fat body TGs revealed that all Locmi-AKHs mobilize the DGs selectively with the preference of those possessing the C18 and C16 FAs. (3) A distribution of FAs in the DG structures indicated a certain degree of Locmi-AKH selectivity toward the mobilized DGs and hence the FAs. The Locmi-AKH-I significantly prefers mobilization unsaturated, while Locmi-AKH-II and -III mobilization of saturated FAs.
