Long-chain fatty aldehydes, biogeneration

Alcohol acetyl transferase genes and ester formation in brewer s yeast—Continued ATFl gene regulation and promoter replacement, 203-205/ cloning of ATFJ genes, 197-199,204 experimental description, 197 Aldehydes, long-chain fatty, biogeneration via oxylipins in edible seaweeds, 146-164... 

Unsaturated and saturated fatty aldehydes such as (Z, Z, Z)-8, 11, 14-heptadecatrienal, (Z, Z)-8, 11-heptadecadienal, (Z)-8-heptadecenal, (Z, Z, Z)-7, 10, 13-hexadecatrienal, pentadecanal, ( , Z, Z)-2, 4, 7-decatrienal, ( , Z)-2, 6-nonadienal and ( )-2-nonenal have been identified in essential oils from edible seaweeds as characteristic major compounds. The enzymatic formations of the long-chain fatty aldehydes from fatty acids such as linolenic acid, linoleic acid, oleic acid and palmitic acid, respectively, have been demonstrated. Based on enzymatic formation of (2/ )-hydroxy-palmitic acid and 2-oxo-palmitic acid from palmitic acid during biogeneration of pentadecanal and on incubation experiments of synthetic (25)- or (2/ )-hydroxy-palmitic acid and 2-oxo-palmitic acid as substrates with crude enzyme solution of Viva pertusa, the biogeneration mechanism of long chain aldehydes via oxylipins is discussed.
