Shuttle carnitina
WebThe carnitine cycle is necessary to shuttle long-chain fatty acids from the cytosol into the intramitochondrial space where mitochondrial beta-oxidation of fatty acids takes place. The oxidation of fatty acids yields acetyl-coenzyme A (CoA) units, which may either be degraded to CO(2) and H(2)O in the citric acid cycle to produce ATP or converted into ketone bodies … WebAutosomal recessively inherited genetic disorders of all three components of the carnitine shuttle have been described. All three disorders present as defects of long-chain fatty acid oxidation. So far CPT1A is the only known defect affecting CPT1 activity (MIM 255120).

WebOct 1, 2016 · The oxidation of medium- (C6–C10) and short-chain (C4–C6) fatty acids seems largely independent from the carnitine shuttle [19], [66]. Under physiologic conditions, oxidation of long- and medium-chain fatty acids is primarily handled by the mitochondrial β-oxidation system, with only minimal contribution from the peroxisomal system [67].
