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.
His work focused on the role of lipid and lipoprotein metabolism in human disease, [8] and specifically the development of an RBC omega-3 index. [1] [2] [3] In 2009, he chaired an American Heart Association science advisory on Omega-6 fatty acids and cardiovascular disease. [9] He has authored >300 manuscripts in peer-reviewed literature.

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).

Essential fatty acids are necessary for humans but cannot be synthesized by the body and must therefore be obtained from food. Omega-3 and omega-6 are used in some cellular signaling pathways and are involved in mediating inflammation, protein synthesis, and metabolic pathways in the human body. Arachidonic acid (AA) is a 20-carbon omega-6 ...
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.

Fatty acid ratio in food. Proportion of omega-3 to omega-6 fatty acids in a diet. Only two essential fatty acids are known to be essential for humans: alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid). [1] The biological effects of the ω-3 and ω-6 fatty acids are mediated by their mutual interactions.
