L-carnitine promotes energy production in cells by transporting fatty acids into the mitochondrion. Its primary function is to transfer long-chain fatty acids across the inner mitochondrial membrane. Fatty acid molecules are activated to coenzyme A (CoA) esters in the cytoplasm of the cell, and then esterified to L-carnitine. The combination of a fatty acid molecule and L-carnitine is called “acyl-carnitine.” Much of the body L-carnitine content is stored in the form of acyl-carnitine. The mitochondrion is the cell’s energy-generating furnace. Called an “organelle,” the mitochondrion is a self-contained structure inside the cell. Like all cellular structures, the mitochondrion is surrounded by a membrane. This membrane is an impenetrable barrier to acyl-CoA esters; passage across the membrane requires L-carnitine as a transporter. On the inside of the mitochondrial membrane, the acyl-CoA esters are made available to be metabolized through the process of beta oxidation. One of the key metabolic byproducts of this process is acetyl-CoA, also called “active acetate,” which enters the Krebs cycle (also known as the “citric acid cycle”) to supply fuel for production of ATP, the cell’s primary energy “currency.” L-Carnitine shuttles excess fatty acid residues out of the mitochondrion and in this role is essential for preventing toxic buildup of fatty acids inside the mitochondrion.
