Acetylenic compounds especially acetylenic fatty acids (Cl, to Cz1) were first of all identified in higher plants. Their structure is very different with regard to the number of the double and triple bonds per molecule, and the functional groups. The mechanism of the biogenesis and the influencing

the Renards procedure which estimates the presence of arachidic and lignoceric acids can be adapted to chromatographic technique such as described. The lead salt separation which also separates trans acids e.g. isooleic acid from hydrogenated fats and high molecular weight monoethenoid acids e.g. erucic acids can be followed by thin-layer chromatography on silver nitrate impregnated plates as described by B. Delrries" for the detection of such acids.

Four acetylenic fatty acids [ll-octadecen-9-ynoic acid (E) (ximenynic acid), 11-octadecen-9-ynoic acid (Z), 9,Il-octadecadiynoic acid and 13-octadecen-9,ll-diynoic acid (E) (exocarpic acid)] were found in the seed oil of Curupiru &fcmFis (Olacaceae) as minor compounds. The mass spectra of the methyl
The diffusion of the sodium salt of monocarboxylic fatty acids, from formate to stearate, has been studied as a function of water content and pH in lecithin-water lamellar phases. Evolution of the diffusion coefficients with increasing chain length reflects the different localizations of fatty acid
The N.M.R. spectra of the cis octadecenoic (A2-A17), octadecynoic (A2-A 5, AlΒ°), and dodecynoic (A s\_ A ll) acids have been recorded. Those with unsaturation near the centre of the molecule cannot be distinguished from one another but the four isomers with unsaturation closest to the carboxyl group
