Biochemical function of eicosanoids

WebMoreover, eicosanoids are recognized as naturally occurring active substances produced by many organs and affecting multiple functions. The situation is much easier for hormones produced by specialized organs, where removal of the endocrine gland generally gives information about its biological significance. Eicosanoids are signaling molecules made by the enzymatic or non-enzymatic oxidation of arachidonic acid or other polyunsaturated fatty acids (PUFAs) that are, similar to arachidonic acid, around 20 carbon units in length. Eicosanoids are a sub-category of oxylipins, i.e. oxidized fatty acids of diverse carbon units in length, and are distinguished from other oxylipins by their overwhelming importance as cell signaling molecules. Eicosanoids function in diverse physiologic…
