omega-3 fatty acid
omega-3 fatty acidn. Any of several polyunsaturated fatty acids that are essential for human metabolism, have anticoagulant properties, and are found in leafy green vegetables, vegetable oils, nuts, and fish such as salmon and mackerel. Increasing dietary intake of omega-3 fatty acids can decrease serum concentrations of triglycerides and LDL cholesterol while increasing HDL cholesterol.
[So called because the first double bond in the chain of carbon atoms in such fatty acids is found between the third and fourth atoms when counted from the omega end of the chain.]omega-3 fatty acid n (Cookery) an unsaturated fatty acid that occurs naturally in fish oil and is valuable in reducing blood-cholesterol levels o•me′ga-3 fat′ty ac′id (oʊˈmi gəˌθri, oʊˈmeɪ-, oʊˈmɛg ə-)
n. a fatty acid found esp. in fish oil and valuable in reducing cholesterol levels in the blood.

omega-3 fatty acidn. Any of several polyunsaturated fatty acids that are essential for human metabolism, have anticoagulant properties, and are found in leafy green vegetables, vegetable oils, nuts, and fish such as salmon and mackerel. Increasing dietary intake of omega-3 fatty acids can decrease serum concentrations of triglycerides and LDL cholesterol while increasing HDL cholesterol.omega-3 fatty acid, ?-3 fatty acidAny of the long-chain polyunsaturated fatty acids found in the oils of some saltwater fish, and in canola, flaxseed, walnuts, and some vegetables. These acids include eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Alpha-linolenic acid (found in flaxseed and chia) can be metabolically converted to omega-3 fatty acids in the body. People whose diets are rich in omega-3 fatty acids have a reduced incidence of cardiovascular disease. Synonym: n-3 fatty acidSee also: acidomega-3 fatty acid
