Chemical Reaction
Nitric oxide synthases produce NO by catalysing a five-electron oxidation of a guanidino nitrogen of -arginine (-Arg). Oxidation of -Arg to -citrulline occurs via two successive monooxygenation reactions producing Nω-hydroxy--arginine (NOHLA) as an intermediate. 2 mol of O2 and 1.5 mol of NADPH are consumed per mole of NO formed.

Famous quotes containing the words chemical and/or reaction:
“We are close to dead. There are faces and bodies like gorged maggots on the dance floor, on the highway, in the city, in the stadium; they are a host of chemical machines who swallow the product of chemical factories, aspirin, preservatives, stimulant, relaxant, and breathe out their chemical wastes into a polluted air. The sense of a long last night over civilization is back again.”
—Norman Mailer (b. 1923)
“The excessive increase of anything often causes a reaction in the opposite direction.”
—Plato (c. 427–347 B.C.)
