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.
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).

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.
Omega-3 fatty acids have a double bond three carbons away from the methyl carbon, whereas omega-6 fatty acids have a double bond six carbons away from the methyl carbon. The illustration below shows the omega-6 fatty acid, linoleic acid. Polyunsaturated fatty acids can be classified in various groups by their chemical structure:
In general, the healthiest fish and shellfish are: High in omega-3 fatty acids. High in protein. Low in mercury. Sustainable. The healthiest seafood choices are very high in omega-3s, says Patton ...
Anti-Inflammatory Foods to Focus On. Fish, especially fish rich in omega-3 fatty acids, such as salmon and tuna. Shellfish. Fruits. Vegetables, especially dark-colored vegetables, like sweet ...
Saturated fatty acids in perilla oil are mainly palmitic (4-9%) and stearic (1-4%). Monounsaturated fatty acids in perilla oil are oleic (13-18%), while polyunsaturated fatty acids in perilla oil are linoleic (14-20%) and linolenic acids (54-64%). [4] In comparison to other plant oils, perilla oil exhibits one of the highest proportion of omega ...
Omega-3 fatty acids are an important part of the human diet, and they play a crucial role in many bodily systems, including heart, brain and joint function. These fats—found in a variety of ...
