Original title:
Analysis of lipids mobilized by adipokinetic hormones in the firebug Pyrrhocoris apterur (Heteroptera: Pyrrhocoridae)
Authors: BÁRTŮ, Iva
Document type: Rigorous theses
Year: 2010
Language: eng
Abstract: An effect of two adipokinetic hormones (Pyrap-AKH and Peram-CAH-II) on distribution of diacylglycerol (DG) molecular species and their fatty acid (FA) constituents were investigated by liquid chromatography (HPLC) - electrospray ionization mass spectrometry (ESI-MS) in haemolymph of the firebug Pyrrhocoris apterus. The results show that DGs with characteristic FAs are preferentially mobilized from fat body (FB) by the action of both AKHs produced by P. apterus. Both the macropterous and brachypterous morphs show very close DG and FA profiles. A separate action of the Pyrap-AKH and the Peram-CAH-II, however, exerts distinct differences in FA distribution at the macropterous morph. It seems that partially C16 and mainly unsaturated C18 FAs play a dominant role in the AKH action with an exclusive position of linoleic acid (18:2) which represents 50 - 60% of the total DG mobilization. The metabolically active C16 and C18 FAs are preferentially absorbed from the linden seeds and accumulated in the FB.
