The lipids of the common house cricket,Acheta domesticus L. II. Hydrocarbons.
The hydrocarbons of the common house cricketAcheta domesticus L. consist ofn-alkanes (4%), 2-methylalkanes (20%), x-methylalkanes (59%), an unidentified series of alkanes (trace), and olefins (16-185). The major n-alkane isn-nonacosane (3.5%). The major 2-methylalkanes are 2-methyloctacosane (8%) and 2-methyltriacontane (11%). The members of the homologous x-methylalkane series consist of mixtures of methylalkanes in which the methyl side-chain is located on the 13th, 15th, and 17th carbon atom in the chain. The major x-methylalkanes are the homologues containing 31 (3%), 33 (6.5%), 35 (12.5%), 37 (27%), and 39 (2.5%) carbon atoms. The olefins are a mixture of straight-chain and 2-methyl-alkenes and alkadienes. The major olefins contain 31 (3%) and 37 (7.5%) carbon atoms.
