What is the Origin of Arachidonic Acid?

The name "arachidonic" is etymologically linked to the plant genus Arachis, which includes the peanut, though in human physiology, it is primarily derived from the dietary intake of animal fats and the subsequent metabolic conversion of linoleic acid. As a fundamental structural component of the cell membrane, its biological origin lies in the essential omega-6 fatty acid pathway. The discovery and subsequent biochemical characterization of AA were instrumental in advancing the understanding of lipid-mediated inflammation.

What is the Mechanism of Arachidonic Acid?

Arachidonic Acid is liberated from the cell membrane phospholipids by the enzyme phospholipase A2 in response to various cellular stimuli, including specific hormonal and inflammatory signals. Once released into the cytoplasm, AA is rapidly metabolized by the cyclooxygenase (COX) and lipoxygenase (LOX) enzymatic pathways. These enzymatic reactions yield a diverse array of eicosanoids, which function as autocrine and paracrine hormones, mediating localized physiological responses such as fever, pain transmission, platelet aggregation, and the critical inflammatory processes required for tissue healing.

Arachidonic Acid

Meaning

Arachidonic acid (AA) is a polyunsaturated omega-6 fatty acid found ubiquitously within the phospholipid bilayer of all cell membranes, with particularly high concentrations noted in neural, muscular, and hepatic tissues. This essential fatty acid serves as a crucial precursor molecule for the biosynthesis of eicosanoids, which are powerful, localized signaling molecules including prostaglandins, thromboxanes, and leukotrienes. The metabolic derivatives of AA are pivotal in regulating inflammatory responses, vascular tone, and numerous hormonal signaling cascades throughout the body.
