polyunsaturated fatty acid A fatty acid containing more than one double bond (C=C). The essential fatty acids omega-3 and omega-6 are polyunsaturated fatty acids (PUFAs) that contain 2 or more cis double bonds. Dietary intake of some PUFAs may have beneficial effects on blood pressure, serum lipds, and inflammation. Some PUFAs, such as omega-3 PUFAs, may have antineoplastic or chemopreventive activities. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
