b-Oxidation of odd-carbon fatty acid chain produces:: (A) Succinyl CoA, (B) Propionyl CoA, (C) Acetyl CoA, (D) Malonyl CoA
Answer is B. Ans. B. Propionyl CoAb-Oxidation is the oxidation of carbon which is adjacent to a-carbon atom. It takes place in the mitochondria. b-Oxidation is accomplished by repetitive 4 steps to finally get Acetyl CoA (from even chain fatty acids) and propionyl CoA (from odd chain fatty acids). The four main steps are dehydrogenation, hydration, oxidation and thiolytic cleavage.
