Carnitine helps in
Fatty acids are activated in the cytoplasm, but the beta-oxidation is in mitochondria. So transpo of fatty acids through the mitochondrial membrane is essential. The long chain fatty acyl CoA cannot pass through the inner mitochondrial membrane. Therefore a transpoer, carnitine is involved in transfer of fatty acids. Carnitine is beta-hydroxygamma- trimethyl ammonium butyrate,Ref: DM Vasudevan - Textbook of Biochemistry, 6th edition, page no: 131
