Webα -Oxidation is important in the catabolism of branched-chain fatty acids. The general reaction, catalyzed by a monooxygenase, requires O 2, Fe 2+, and either ascorbate or tetrahydropteridine. It has been demonstrated in plants and in microsomes from brain and other tissues. This reaction is also a route for the synthesis of hydroxy fatty acids. WebStage 1: Beta oxidation (Fatty acid oxidation): Two types of product are formed. The carbon atoms are converted to acetyl CoA, which is fed into the citric acid cycle. The …
