Methyl «-octadecanoate

Quantitative changes in lipid compounds on the silk and cuticle of females correlate significantly with changes in female sexual receptivity in spiders. For example, female T. atrica attach a contact sex pheromone to their web (Trabalon et al., 1997,2005 Prouvost et al., 1999). This pheromone consists of a complex mixture of saturated hydrocarbons, methyl esters (methyl tetradecanoate, methyl pentadecanoate, methyl hexadecanoate, and methyl octadecanoate) and their fatty acids (tetradecanoic, pentadecanoic, hexadecanoic, and cis,cis-9,12-octadecadienoic acids). The female uses cuticular compounds, which are applied to the silk in substantial amounts during web construction. Modification of chemical profiles makes the female attractive to males (Trabalon et al., 2005). Receptive females are different to unreceptive ones with respect to three fatty acids (hexadecanoic, octadeca-dienoic and octadecenoic acids) and three methyl esters (linoleate, oleate, and stearate) present on both the web and the cuticle. Our combined results from chemical analyses and behavioral assays demonstrate clearly that these contact compounds are quantitatively correlated with the behavior of spiders. [Pg.353]

The mycobacterial cell wall contains the essential lipoglycan structures lipoarabinomannan, lipomannan, and phosphatidyl-my6>-inositol-mannosides (PIMs) [262]. These molecules are attached to the cytoplasmic membrane and extend through the cell wall into the extracellular environment (O Fig. 1). PIMs, LMs, and LAMs are attached to the cytoplasmic membrane by a conserved anchor, which consists of an sn-glycero-3-phospho-(l-D-my6>-inositol), with a single cx-D-Man/> linked at C2 of the my6>-inositol (O Fig. 19c). The mannan core is attached to C6 of the my6>-inositol unit. There are four potential sites of fatty acid attachment on the anchor both free hydroxyls of the glycerol unit, C6 of the Man/ linked to C2 of my6>-inositol and C3 of the my6>-inositol. The fatty acids are most commonly palmitic and tuberculostearic (10-methyl-octadecanoic) acids, and less frequently, stearic acid. Other fatty acids are seen in... [Pg.1574]

The fatty acid content is given as per cent of the total fatty acid content of the respective phospholipids. The iso-acids were identified by their retentions times in GLC to have the following chain lengths lO-methyl-undecanoic acid (iso-lauric) 12-methyl-tridecanoic acid (iso-iayristic)j 14-methyl-pentadecanoic acid (iso-palmitic) 16-methyl-heptadecanoic acid (iso-stearic) 20-methyl-heneicosanoic acid (iso-behenic). The anteiso-acids were 12-me-thyl-tetradecanoic acid 14-methyl-hexadecanoic-acid 16-methyl-octadecanoic acid 19-methyl-heneicosanoic acid. [Pg.199]
