Omega-6 fatty acids


Omega-6 fatty acids are so called because the very first double bond occurs at the 6th carbon from the omega end. The significant omega-6 fatty acids are: Linoleic acid (LA) – the ‘parent’ short-chain omega-6 fatty acid found mainly in flaxseed, canola and soybean oils. g-linolenic acid (gamma-linolenic acid or GLA) is a short-chain omega-6 fatty acid found in borage, evening primrose and black current seed oils. Di-homo g-linoenic acid (DGLA) is a long-chain omega-6 fatty acid found in meat, poultry and eggs. DGLA is the precursor to the series-1 prostaglandins and series-1 thromboxanes. Arachidonic acid (AA) is a long-chain omega-6 fatty acid found in meat, poultry and eggs. AA is the precursor to the series-2 prostaglandins, series-2 thromboxanes and series-4 leukotrienes.
