Detailed explanation-1: -Carnitine is essential for the transfer of long-chain fatty acids across the inner mitochondrial membrane for subsequent -oxidation . It can be synthesized by the body or assumed with the diet from meat and dairy products.

Detailed explanation-2: -Carnitine. Carnitine transports fatty acids into mitochondria.

Detailed explanation-3: -Carnitine has two principal functions in the organism. One is to transport long-chain fatty acids into the mitochondrion. The second function of carnitine is to regulate the intramitochondrial ratio of acylocoenzyme A to free coenzyme A.

Detailed explanation-4: -The carnitine/acylcarnitine carrier (CAC) is a transport protein of the inner mitochondrial membrane that belongs to the mitochondrial carrier protein family.

Detailed explanation-5: -Fatty acyl carnitine is transported across the inner mitochondrial membrane in exchange for carnitine by an antiport translocase. In the mitochondrial matrix fatty acyl carnitine reacts with CoA in a reaction catalyzed by carnitine acyltransferase II (CAT-II), yielding fatty acyl CoA and carnitine.
