Mitochondrial Fatty Acid Oxidation• Mitochondrial fatty acid oxidation requires:– Carnitine shuttle• Active transport mechanism• Facilitates entry of long chain fatty acids acyl CoAspecies into mitochondrion• Not required for medium/short chain species ( < C12) -free passage– b-oxidation spiral• For acids with 20 or less carbons• Series of reactions that sequentially shorten the carbonskeleton• Generate acetyl-CoA as end product
