Eicosanoid Pathways

Meaning

A complex network of biochemical cascades responsible for the synthesis and metabolism of eicosanoids, which are signaling molecules derived from 20-carbon polyunsaturated fatty acids, such as arachidonic acid. These pathways produce potent, short-acting lipid mediators like prostaglandins, thromboxanes, and leukotrienes. Eicosanoids act locally to regulate inflammation, vascular tone, and immune response.
