Figure 2: β-oxidation of fatty acids. Role of carnitine in the transport of fatty acids – Carnitine shuttle. Acyl-CoA is converted to acetyl-CoA through dehydration, hydration, oxidation and thiolysis. Acetyl-CoA can enter the Krebs cycle or can lead to ketogenesis. CPT-I, Carnitine palmitoyltransferase-I, CPT-2 – Carnitine palmitoyltransferase -2, MCAD - Medium-chain Acyl-Co A dehydroxgenase, LCHAD - Long - chain3-hydroxyacyl-CoA dehydrogenase.
