Fatty acids are activated to acyl-coas and the acyl group is further transferred to carnitine because acyl-carnitines readily cross the mitochondrial inner membrane, but acyl-CoAs do not.

What part does carnitine play in the movement of fatty acids?

  • Transferring long-chain fatty acids to mitochondria for ensuing -oxidation is the primary role of carnitine. As a scavenger, carnitine also binds acyl residues from the intermediate metabolism of amino acids and aids in their removal.
  • In mammals, carnitine operates by having its 3-hydroxyl group reversibly esterified by fatty acyl-CoA esters, followed by the production of acylcarnitines and their subsequent transfer from one cellular compartment to another.
  • According to the cellular location and metabolic goal, the family of enzymes known as carnitine acyltransferases has specificities for a wide range of acyl chain lengths of fatty acids, including those with different chain lengths, branching patterns, and other functional groups.
  • They allow for the reversible transfer of acyl groups between carnitine and free CoA. Thus, carnitine is necessary for the export of acetyl- and other short-chain acyl groups from peroxisomes as well as the transportation of fatty acyl groups into mitochondria and the removal of any excess acyl groups.
