docosahexaenoic acid

docosahexaenoic acid
an omega-3-fatty acid found in fish which protects ageing rodent brains from the clumping seen in Alzheimer\'s disease. This chemical is formed in microalgae of the genus Schizochytrium and concentrated up the food chain to fish and other organisms. Chemical name is all-cis-docosa-4,7,10,13,16,19-hexaenoic acid. May account for the reduction in risk of dementia and stroke in humans as a diet of fish replaces DHA lost in ageing. Also called dervonic acid. Abbreviated as DHA
