The distribution in lipid classes of fatty acids biosynthesized by the black cricket melanogryllus desertus pall.(Orthoptera:Gryllidae)

Kazein esaslı yağsız sentetik besin üzerinde yetiştirilen Melanogıyllus desertus' (karaçekirge) un bir günlük ergin bireylerinin, fosfolipit, monoaçilgliserol, diaçilgliserol ve triaçilgliserol gibi çeşitli lipit sınıflarının yağ asiti içerikleri gaz kromatoğrafisi metodu ile analiz edildi. Çeşitli lipit sınıfları arasında, böcek tarafından sentezlenen bazı yağ asitlerinin konsantrasyonları bakımından önemli farklar bulundu. Linoleik asit (18:2n-6), diğer fraksiyonlara oranla fosfolipit fraksiyonunda daha fazladır (%50). Monoaçilgliserol ve diaçilgliserol fraksiyonlarında en aktif sentezlenen yağ asiti palmitik (16:0) asittir. Triaçilgliserolde ise en fazla bulunan yağ asidi ise oleik (18:1) asittir.

Melanogryllus desertus Pall.(Orthoptera:Gryllidae)'un sentezlediği yağ asitlerinin lipid sınıflarındaki dağılımı

The fatty acid compositions of various lipid classes such as phospholipid, monoacylglycerol, diacylglycerol and triacylglycerol in one-day old adults of the black cricket Melanogryllus desertus reared on fat-free artificial diet based on casein were analyzed by gas chromatographic methods. There were significant differences among various lipid classes with respect to concentrations of some fatty acids biosynthesized by the insect, with linoleic acid being much more abundant in phospholipid fraction (50 %) than other fractions. In the monoacylglycerol and diacylglycerol fractions, palmitic acid was the most actively biosynthesized fatty acid. In the triacylglycerol, oleic acid predominated.
