WebEicosanoids are potent chemical messengers that have well-established roles in regulation of inflammation, immunity, platelet aggregation, smooth muscle contraction and renal function (Nicolaou and Kafatos, 2004 ). They include prostaglandins, thromboxanes and leukotrienes and are usually produced from the omega-6 fatty acid arachidonic acid. WebEicosanoids are inflammatory mediators primarily generated by hydrolysis of membrane phospholipids by phospholipase A2 to ω-3 and ω-6 C 20 fatty acids that next are converted to leukotrienes (LTs), prostaglandins (PGs), prostacyclins (PCs), and thromboxanes (TXAs). ibiza drinks restrictions
