摘要

Prostaglandin H synthase (PGHS) catalyzes the conversion of arachidonic acid to prostaglandin G2 in the cyclooxygenase reaction. The first step of the mechanism has been proposed to involve abstraction of the pro-S hydrogen atom from C13 to generate a pentadienyl radical spanning C11-C15. We report here the synthesis of six site-specifically deuterated arachidonic acids to investigate the structure of the radical intermediate. The ...
