Docosatetraenoic acid is a long-chain, polyunsaturated fatty acid in the omega-6 fatty acid group . It is among the polyenoic and she is a Isolensäure because their four cis - double bonds in each case by a methyl group are separated. One isomer is the trans fatty acid (4 Z , 7 Z , 10 Z , 13 E ) -docosatetraenoic acid.

It occurs esterified as triacylglyceride in algae , sponges and the innards of ruminants , in meat, fish, eggs and fish oils in small amounts. But it also occurs in a few plant species. The fatty acid occurs in the human organism - chemically bound - in the cell membranes of the red blood cells and especially in the human brain, where it is built up from arachidonic acid by lengthening the carbon chain by two -CH2 groups . Overall, these two fatty acids together make up 90% of the ω-6 fatty acids in brain tissue.
