Arachidonic acid is a polyunsaturated fatty acid that plays a crucial role in the body. It is primarily found in the phospholipids of cell membranes and is derived from dietary sources such as meat, eggs, and certain fish. This fatty acid is important for producing signaling molecules called eicosanoids, which are involved in various physiological processes, including inflammation and immune responses. In addition to its role in inflammation, arachidonic acid is also essential for brain function and development. It contributes to the formation of neural membranes and is involved in neurotransmission. The balance of arachidonic acid and its metabolites is vital for maintaining overall health and preventing chronic diseases.
