Docosahexaenoic acid （DHA； 22:6.omega.3） is one of the essential dietary .omega.-3 unsaturated fatty acids and the preferred n-3 fatty acid for development of the brain and retina. 4，5-dehydro DHA is a novel analog of DHA in which the double bond closest to the carboxyl group has been converted into an acetylene. 4，5-dehydro DHA is a novel compound that has not been studied in biological systems. However， the corresponding acetylene in the C-20 fatty acid series （5，6-dehydro arachidonic acid） is a well known inhibitor of 5-lipoxygenase.
