The epoxyeicosatrienoic acids (EETs) are eicosanoids produced by cyochrome P450 epoxygenase. They act as “short range” hormones in the cardiovascular system & kidney where they produce vasodilation by causing activation of Ca-activated K channels (Smyth & FitzGerald, 2012; ).

Others include serotonin a neurotransmitter derived from tryptophan, thyroid hormones derived from tyrosine, and histamine derived from histidine. All except thyroid hormones are hydrophilic (lipophobic).

Eicosanoids are not stored within cells, and are synthesized as needed when their biosynthesis is activated by trauma or cytokines which activate phospholipase A2 (PLA2). Fatty acids that are cleaved by PLA2 from cell membranes are then oxygenated by one of three different families of enzymes to produce eicosanoids (Figure 1).

An important group of these are the catecholamines which contain a 6 carbon ring (catechol) and are derived from tyrosine.
Eicosanoids are signaling molecules derived from the oxidation of arachidonic acid

Eicosanoids- Subjective Questions

About 40% of the bodies caloric intake is derived from lipids and almost all of these calories come from fats, the . The fatty acid composition in terms of saturation (oxidation forms) is not uniform but varies with the origin. Plant fats contain more polyunsaturated fatty acids and animal fats contain more saturated fatty acids as well as cholesterol. Polyunsaturated fats are essential for humans because animals are not able to synthesize those on their own. Most lipids, however, have metabolic functions contributing to membrane structures and signaling. (C20:4) is a fatty acid which plays a central role as precursor for prostaglandin synthesis. Phospholipids are synthesized from diacylgycerolphosphate, a negatively charged phospholipid precursor and signaling molecule itself, carrying various hydrophilic and/or charged headgroups that determine the surface charge and chemical properties of biological membrane surfaces.
