Benzaldehyde is the compound principally responsible for the odor of almonds. What product is formed when benzaldehyde is treated with H2, Pd?

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. Rate of formation of PGG2 with 10 mg/ml ibuprofen (mM/min) Arachidonic acid (mM) Rate of formation of PGG2 (mM/min) 0.190 12.3 0.228 13.9 0.342 17.5 0.570 1.33 22.2 28.8 7.71 8.88 11.9 16.3 24.0 The kinetic data given in the table are for the reaction catalyzed by a mutant of prostaglandin endoperoxide synthase. Focusing here on the first two columns, determine the Vmax and Km of the enzyme. Vmax Km = mM/min mM
