6. Delineate the steps in the production by a human of a C20:3 45, 8, 11 fatty acid. Make sure your
scheme is metabolically plausible. For each step, list the enzymes, cofactors, and product(s).
You may start from palmitate, if that is useful. If you require an alternate starting material,
identify the material and explain why you chose that material.

- 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 re-sponsible 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 en-doperoxide 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). a)The kinetic data given below are for the reaction catalyzed by prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. b)Ibuprofen is an inhibitor of prostaglandin endoperoxide synthase.
