Study Notes
Eicosanoid Synthesis and Function
- Phospholipase A2 is the enzyme responsible for releasing eicosanoids from cell membranes.
- Eicosanoids are synthesized and released in response to inflammation, injury, or immune response.
- Prostaglandin E2 (PGE2) is cytoprotective in the stomach, protecting it from acid and other damages.
- The primary function of thromboxane (TxA2) is to induce platelet aggregation and vasoconstriction.
- Eicosanoids are synthesized from arachidonic acid, a 20-carbon fatty acid derived from phospholipids in cell membranes.
