Shuttle carnitina
Detto anche sistema navetta, è una serie di tre reazioni enzimatiche che hanno come scopo quello di far passare attraverso la membrana mitocondriale gli acidi grassi con 14 o più atomi di carbonio (quelli con 12 o meno atomi di carbonio possono entrare nei mitocondri senza l'aiuto di trasportatori di membrana). 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].
