ArachidonsäureEthylester

Arachidonic acid is a polyunsaturated omega-6 fatty acid with 20 carbon atoms and four cis double bonds. It is a crucial component of cell membranes in the brain and muscles, and it plays a significant role in various physiological processes. In the human body, arachidonic acid is synthesized from linoleic acid, an essential fatty acid that must be obtained from the diet.

Arachidonic acid serves as a precursor for several signaling molecules, including prostaglandins, thromboxanes, and leukotrienes. These eicosanoids are involved in inflammation, immune response, blood clotting, and pain sensation. For instance, prostaglandins can cause vasodilation and fever, while leukotrienes are potent mediators of allergic reactions and inflammation.

Dietary sources of arachidonic acid include animal products such as meat, eggs, and dairy. While essential for certain bodily functions, excessive intake of arachidonic acid has been linked to inflammatory conditions. Research continues to explore the complex roles of arachidonic acid in health and disease, particularly its involvement in neurological function and inflammatory pathways. Its metabolism is tightly regulated to maintain homeostasis.
