omega-3 fatty acid

n.
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.]
