Synthesis of the ω6 (5z,8z)-tetradecadienoic and (7z,10z)-hexadecadienoic polyene fatty acids

An approach using acetylenes was used and optimized to synthesize rare natural ω6 polyene fatty acids. The key synthetic step was cross-coupling of a propargyl derivative with a terminal acetylene in the presence of equimolar amounts of Cu(I).

SPECIFICITY OF THE ENZYME SYSTEM PRODUCING LONG CHAIN ALDEHYDES IN THE GREEN ALGA, ULVA PERTUSA

The greater part of the enzyme activity producing long chain aldehydes (LCA) such as (8Z)-heptadecanal, (8Z,11Z)-heptadecadienal, (8Z,11Z,14Z)-heptadecatrienal was found in the 4000 g precipitate of homogenates of the green alga, Ulva pertusa.The LCA-forming activity was readily solubilized from the precipitate by addition of 0.2percent Triton X-100.The solubilized LCA-forming activity showed an optimum pH in the range 8.5-9.5. α-Linolenic acid was a very good substrate, but γ-linolenic acid was a poor substrate for the activity.Linoleic acid was the best substrate of an entire series of (ζ6Z, ζ9Z)-dienoic acids, in which the chain length varied from C13 to C20.Key Word Index - Ulva pertusa; green alga; odour; aldehydes; fatty acids; substrate specificity.
