Disease Roles
Arachidonic acid Overview
Arachidonic acid is a polyunsaturated omega-6 fatty acid and a key precursor in the prostaglandin synthesis pathway. It is released from membrane phospholipids and converted into various prostanoids, including prostaglandins, thromboxanes, and prostacyclins, which mediate inflammation, pain, and other physiological processes.
