Arachidonic acid is a type of polyunsaturated fatty acid that is essential for the human body. It plays a vital role in various physiological processes, including inflammation, blood clotting, and immune system function. In this article, we will explore the definition and meaning of arachidonic acid, its origin, associations, synonyms, antonyms, and example sentences.
Definitions
Arachidonic acid is a 20-carbon fatty acid that is derived from dietary sources, such as meat, eggs, and dairy products. It is also synthesized in the body from linoleic acid, an essential fatty acid that cannot be produced by the body. Arachidonic acid is a precursor to various bioactive molecules, including prostaglandins, thromboxanes, and leukotrienes, which are involved in inflammation, pain, and fever.
Origin
Arachidonic acid was first discovered in 1902 by George and Mildred Burr, who identified it as a component of the fat in the brain and liver of cows. They named it after the Greek word “arachis,” which means peanut, as it was also found in high amounts in peanuts. Later, it was found to be present in many other foods, including meat, eggs, and dairy products.
