Essential fatty acids play a part in many metabolic processes, and there is evidence to suggest that low levels of essential fatty acids, or the wrong balance of types among the essential fatty acids, may be a factor in a number of illnesses.
Chemically, arachidonic acid is a carboxylicacid with a 20-carbon chain and four cis double bonds; the first double bond is located at the sixth carbon from the omega end.
Arachidonic acid is a polyunsaturated fattyacid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine and phosphatidylinositides) of membranes of the body's cells, and is highly enriched in the brain.
Arachidonic acid is freed from phospholipid molecule by the enzyme phospholipase A2.
