Study Notes
Prostaglandin Formation
- Cyclooxygenase is the enzyme involved in the formation of prostaglandins from arachidonic acid.
Gastric Function
- Prostaglandin E2 is the main prostaglandin involved in reducing acid secretion and increasing mucus secretion in the stomach.
Cyclooxygenase Forms
- Cyclooxygenase-2 (COX-2) is induced during inflammation by cytokines and endotoxins.
Lipoxygenase Pathway
- Leukotrienes are the class of substances obtained from arachidonic acid by the action of lipoxygenase.
Prostaglandin Biosynthesis
- Arachidonic acid is the precursor for the biosynthesis of all prostaglandins.
