Enzymatic formation of unsaturated long chain fatty aldehydes in Ulva pertusa

(Z)-8-Heptadecenal, (Z,Z)-8, 11-heptadecadienal and 8,11,14-heptadecatrienal, were produced enzymatically from oleic, linoleic and linoleni.

Concise synthesis of (8Z,11Z,14Z)-8,11,14-heptadecatrienal, (7Z,10Z,13Z)-7,10,13-hexadecatrienal, and (8Z,11Z)-8,11-heptadecadienal, components of the essential oil of marine green alga Ulva pertusa

The long-chain aldehydes, (8Z,11Z,14Z)-8,11,14-heptadecatrienal, (7Z,10Z,13Z)-7,10,13-hexadecatrienal, and (8Z,11Z)-8,11-heptadecadienal, were concisely synthesized by using Grignard coupling, catalytic hydrogenation with the Lindlar catalyst, and oxidation with Dess-Martin periodinane as the key steps. Particularly, (8Z,11Z,14Z)-8,11,14-heptadecatrienal and (7Z,10Z, 13Z)-7,10,13-hexadecatrienal both possessed a seaweed-like odor.

Abnormal Catabolites of Unsaturated Fatty Acids by In Vitro Reaction of Crude Enzyme from Infected Higher Plants

The reaction of α-linolenic acid with crude enzyme (lipoxygenase) obtained from infected pumpkins led to the formation of 8Z,11Z,14Z-heptadecatrienal (noraldehyde) and its acid (noracid) in addition to 13S-hyroperoxy linolenic acid.Since the noraldehyde and its acid were also isolated from the crude enzyme reaction of other infected plants, their formation seems to be related with the pathogen-infection of higher plants.

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.
