![5. Properties of an Enzyme of Prostaglandin Synthesis Prostaglandins are
a class of eicosanoids, fatty acid derivatives with a variety of extremely
potent actions on vertebrate tissues. They are responsible for producing
fever and inflammation and its associated pain. Prostaglandins are derived
from the 20-carbon fatty acid arachidonic acid in a reaction catalyzed by
the enzyme prostaglandin endoperoxide synthase. This enzyme, a
cyclooxygenase, uses oxygen to convert arachidonic acid to PGG2, the
immediate precursor of many different prostaglandins (prostaglandin
synthesis is described in Chapter 21).
