Abstract geometric shape
Cyclooxygenase (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, EC 1.14.99.1) that is responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin, from arachidonic acid. Two COX enzymes are known to be involved in prostaglandin synthesis, COX-1 and COX-2. COX-1 generates prostaglandins that are involved in the protection of gastrointestinal mucosa, while COX-2 generates prostaglandins that mediate inflammation and pain in sites throughout the body.
A model of a molecule of arginine, an amino acid. Amino acids are the building blocks of proteins and have many functions in metabolism. In particular, Arginine has an important function in the immune system, wound healing and cell division.
