| Common Name | Cis-8,11,14,17-Eicosatetraenoic acid |

| Description | Cis-8,11,14,17-Eicosatetraenoic acid is an eicosanoid present in marine lipids, a minor n-3 polyunsaturated fatty acid (PUFA) which is a position isomer of 20:4n-6. n-3 PUFA contained in marine lipids appear to have a protective effect against coronary heart disease and thrombosis. Human platelets metabolize 8,11,14,17-eicosatetraenoic acid primarily into 12-hydroxy-8,10,14,17-eicosatetraenoic acid. The eicosanoids are a diverse family of molecules that have powerful effects on cell function. They are best known as intercellular messengers, having autocrine and paracrine effects following their secretion from the cells that synthesize them. The diversity of possible products that can be synthesized from eicosatrienoic acid is due, in part to the variety of enzymes that can act on it. Studies have placed many, but not all, of these enzymes at or inside the nucleus. In some cases, the nuclear import or export of eicosatrienoic acid-processing enzymes is highly regulated. Furthermore, nuclear receptors that are activated by specific eicosanoids are known to exist. Taken together, these findings indicate that the enzymatic conversion of eicosatrienoic acid to specific signaling molecules can occur in the nucleus, that it is regulated, and that the synthesized products may act within the nucleus.
