Use the priority system to draw the structure of the following molecule:
2-methoxy-3-methyl-5-oxoheptanoic acid
Aspirin is an anti-inammatory agent because it inhibits the conversion of arachidonic acid to prostaglandins by the transfer of its acetyl group (CH3CO –) to an OH group at the active site of an enzyme (Section 19.6). This reaction, called transesterication, results in the conversion of one ester to another by a nucleophilic acyl substitution reaction. Draw a stepwise mechanism for the given transesterication.
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.
