Quizplus · Accepted Answer

Eicosanoids are small lipid molecules that are released by nearly all cells in the body, including immune cells, which are involved in the regulation of inflammation and immunity. Eicosanoids are derived from arachidonic acid, an omega-6 fatty acid, and include prostaglandins, leukotrienes, and thromboxanes. They are involved in a range of physiological processes, such as pain and fever control, blood clotting, and regulation of blood pressure.
