Role of carnitine in lipid metabolism ?
Ans. is 'd' i.e., Transfer of activated long chain FFA into mitochondria Activated long chain fatty acid (acyl CoA) cannot penetrate inner mitochondria! membrane. Acyl group of acyl CoA is transferred to carnitine, resulting in formation of acylcarnitine. Acylcarnitine is then transpoed across the inner mitochondria! membrane into the mitochondria! matrix by translocase. Once inside the mitochondrion, acyl group of acylcarnitine is transferred back to CoA, resulting in formation of acyl-CoA which undergoes 13-oxidation.
