title: Biosynthesis of the novel fatty acid, 17-methyl-cis-9,10-methyleneoctadecanoic acid, by the parasitic protozoan, Herpetomonas megaseliae.
abstract: Herpetomonas megaseliae, a flagellate protozoan parasite of the gut of a dipteran, Megaselia scalaris, is shown by chromatographic, spectrometric and radiotracer methods to synthesize de novo an iso-branched chain cyclopropane fatty acid, 17-methyl-cis-9,10-methyleneoctadecanoic acid.
