As far as possible and customary, SI units are used. Unless otherwise noted, the data given apply to standard conditions .

Eicosatrienoic acid is a long-chain, polyunsaturated fatty acid in the omega-3 fatty acid group . The three double bonds are cis -configured, they are each separated by a methylene group . The trienoic acid is thus one of the isolenic acids .

It occurs esterified as triacylglyceride in small amounts in various types of conifers , but also in other plant species and in microalgae .

Isomers

There are several all- cis 20: 3 (ω − 6) isomers:

Further all- cis isomers are:
