Fatty acids are activated to acyl-CoAs and the acyl group is further transferred to carnitine because:

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. acyl-carnitines readily cross the mitochondrial inner membrane, but acyl-CoAs do not.

  2. acyl-CoAs easily cross the mitochondrial membrane, but the fatty acids themselves will not.

  3. carnitine is required to oxidize NAD+ to NADH.

  4. fatty acids cannot be oxidized by FAD unless they are in the acyl-carnitine form.
