Arakidonihapporasvahappo, commonly known as **arachidonic acid**, is an omega-6 fatty acid found in the cell membranes of animals. It plays a crucial role in various physiological processes, particularly in cell signaling and inflammation regulation. Structurally, it consists of 20 carbon atoms with four cis double bonds, classified as a polyunsaturated fatty acid (PUFA).

Arachidonic acid is derived from dietary sources, primarily linoleic acid (another omega-6 fatty acid), through a series of enzymatic desaturation and elongation steps. It is abundant in animal fats, including those found in meat, dairy products, and eggs, as well as in certain plant oils like safflower and sunflower oil. The human body synthesizes it primarily in the liver and adipose tissue.

This fatty acid serves as a precursor for eicosanoids, a group of hormone-like compounds that mediate inflammation, blood clotting, and immune responses. Key eicosanoids derived from arachidonic acid include prostaglandins, thromboxanes, and leukotrienes. While these compounds are essential for maintaining homeostasis, their overproduction is linked to chronic inflammation and various diseases, such as cardiovascular conditions and autoimmune disorders.

Dietary intake of arachidonic acid is generally considered safe within moderate levels, but excessive consumption may contribute to health risks associated with high omega-6 intake, such as oxidative stress and metabolic dysfunction. Some studies suggest balancing omega-6 with omega-3 fatty acids (e.g., from fish or flaxseed) may help mitigate these effects. Additionally, genetic variations in arachidonic acid metabolism can influence individual susceptibility to related health conditions.

In summary, arachidonic acid is a vital yet complex fatty acid with dual roles in health and disease, requiring careful consideration in dietary and clinical contexts.
