Cyclooxygenase (COX) enzymes are crucial in the biosynthesis of prostaglandins from arachidonic acid. There are two main isoforms: COX-1 and COX-2. COX-1 is constitutively expressed in many tissues and is involved in the regulation of normal physiological processes. COX-2, on the other hand, is inducible and is often associated with inflammation and pain.
