Most eicosanoids are derivates of arachidonic acid.

Explanation:

Eicosanoids are a group of lipid molecules originating from the oxidation of the essential fatty acids of omega-3 and omega-6 carbons. They fulfill extensive functions as mediators for the central nervous system, the events of inflammation and the immune response in both vertebrates and invertebrates.

Eicosanoids are carboxylic acids, by virtue of which they obtain their metabolic properties. Those derived from omega-3 usually have anti-inflammatory peculiarities, not so much those derived from omega-6. Of the eicosanoids, prostaglandins and thromboxanes include saturated and heterocyclic rings, while leukotrienes and hydroxy acids are linear (open from the beginning to the end of their chain). All of them are derived from arachidonic acid, and are essential fatty acids. In addition to arachidonic acid, other essential fatty acids can also serve as precursors in the formation of these molecules, for example, linoleic acid.
