An omega−3 fatty acid is a fatty acid with multiple double bonds, where the first double bond is between the third and fourth carbon atoms from the end of the carbon atom chain. "Short-chain" omega−3 fatty acids have a chain of 18 carbon atoms or less, while "long-chain" omega−3 fatty acids have a chain of 20 or more.
Omega-3-acid ethyl esters are used in addition to changes in diet to reduce triglyceride levels in adults with severe (≥ 500 mg/dL) hypertriglyceridemia. [10] In the European Union and other major markets outside the US, omega-3-acid ethyl esters are indicated for hypertriglyceridemia by itself, or in combination with a statin for people with mixed dyslipidemia.

One 3-ounce serving boasts more than 1,500 mg of omega-3 DHA and EPA combined, making it a top source of omega-3s," says Largeman-Roth. In addition to healthy fats, sablefish is also a good source ...
Mammals are unable to synthesize omega−3 fatty acids, but can obtain the shorter-chain omega−3 fatty acid ALA (18 carbons and 3 double bonds) through diet and use it to form the more important long-chain omega−3 fatty acids, EPA (20 carbons and 5 double bonds) and then from EPA, the most crucial, DHA (22 carbons and 6 double bonds).

In chemical structure, EPA is a carboxylic acid with a 20- carbon chain and five cis double bonds; the first double bond is located at the third carbon from the omega end. EPA is a polyunsaturated fatty acid (PUFA) that acts as a precursor for prostaglandin-3 (which inhibits platelet aggregation), thromboxane-3, and leukotriene-5 eicosanoids.
