Secondary Information

Presence in other biological fluids/tissue/cells located on both sides of the mitochondrial inner membrane,
Protein Function catalyse the reversible transfer of a long-chain fatty-acyl group from acyl-CoA to L-carnitine; facilitate the uptake of long-chain fatty acids into the mitochondrial matrix for oxidation. CPT2(carnitine palmitoyltransferase 2) and CACT(carnitine/acylcarnitine translocase) are crucial for mitochondrial acylcarnitine formation and export to the extracellular fluids in mFAOD.
Biochemical Properties CPT-A (in outer membrane) is more easily removed from rat liver mitochondria by digitonin extraction; CPT-A is strongly inhibited by malonyl-CoA, CPT-B is less sensitive to malonyl-CoA; As found in bovine liver mitochondria, The pl is low (pH 6.0); Km for carnitine increases below pH 7.0;
Significance in milk control lipid metabolism and helps in synthesis of medium chain fatty acids in mammary gland
