Prostaglandins are a class of eicosanoids, fatty acid derivatives involved in a variety of important phenomena, including fever, inflammation, and pain. The first step in prostaglandin synthesis involves the conversion of the 20-carbon fatty acid arachidonic acid to PGG2 by the enzyme prostaglandin endoperoxide synthase, or cyclooxy: Ibuprofen is one of several inhibitors of cyclooxogenase used therapeutically. Arachidonic acid 20₂ 0.5 1.0 1.5 2.5 3.5 cyclooxrygenase PGG₂ JOH محمد The following kinetic data were obtained for the enzyme cyclooxygenase in the absence of any inhibitor (1), and in the presence of ibuprofen (2) at a concentration of 48 [arachidonic acid] (uM) (1) v(uM/min) (2) v(uM/min) 23.5 32.2 36.9 41.8 44.0 16.67 25.25 30.49 37.04 38.91 Ibuprofen A. Plot the data in standard Michaelis-Menten form as well as in double-reciprocal form. B. Determine Vmax and Km for the enzyme. C. Based on this limited data set, what type of inhibition does ibuprofen likely exhibit?…
