The fatty acid compositions of lipid classes in non-esterified fatty acid and in acylglyceroi fractions of Tenebrio molitor L. (Coleoptera: Tenebrionidae) larvae were identified in fat bcdy, haemolymph and muscle by Gas-T iquid Chromatography.
The identified 18 fatty acids had sıraight, mostly odd numbered carbon chains wîth C numbers ranging fi’om 14 tc 22. Some of the n3 and n6 members of polyenoics were also separated.
Quantitative and some gualitative differences wçre observed in fatty aCid compositions between the lipid classes of the same tissue and between a given lipid fraction of ali tissues.
The main saturated fatty acid was C 16:0 in all the lipid classes. Ali the other salurates, namely C 14:0, C 17:0, C 18:0 and C 20:0, were also e isted in various proportions. In FFA fractions C 18:0 was distinctively hıgher than in acylglycerol fractions.
High nnsaturation was observed primarily as a resnlt of high proportions of C 18: 1 an .l C 20:4 n3 in 1,2-JÜGj TG and FFA fractions and in MG and 1,3-DG fractions respectively.
