For instance, in an omega−3 fatty acid with 18 carbon atoms (see illustration), where the methyl end is at location 18 from the carboxyl end, n (or ω) represents the number 18, and the notation n−3 (or ω−3) represents the subtraction 18−3 = 15, where 15 is the locant of the double bond which is closest to the methyl end, counted from ...
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).

Docosapentaenoic acid (DPA) is an n-3 fatty acid that is structurally similar to eicosapentaenoic acid (EPA) with the same number of double bonds, but two more carbon chain units. [4] Dietary sources. These are the top five sources for DPA according to the USDA Agricultural Research Service: [5] Fish oil, menhaden 0.668 g in 1 tbsp. (13.6 g)
