fish oils

views updated

fish oils These contain long‐chain polyunsaturated fatty acids which appear to offer some protection against problems associated with heart disease. The two main ones are EPA (eicosapentaenoic acid; C20 : 5 ω3) and DHA (docosahexaenoic acid; C22 : 6 ω3). Fish oil concentrates containing these fatty acids are sold as pharmaceutical preparations. See also cod liver oil; halibut liver oil; menhaden.
