(±)-Octanoylcarnitine chloride (CAS 14919-35-8) is an acyl derivative structurally related to acetylcarnitine chloride; it functions as an intermediate in fatty acid metabolism by facilitating fatty acid transport across mitochondrial membranes for subsequent β-oxidation and ATP synthesis. Experimental evidence indicates that (±)-octanoylcarnitine modulates mitochondrial utilization of certain branched-chain 2-oxo acids, influencing their oxidation rates in isolated mitochondria. Additionally, researchers employ (±)-octanoylcarnitine combined with malate to investigate mitochondrial respiratory activity, examining oxidative phosphorylation dynamics in response to metabolic modulators, such as ADP and creatine, particularly in isolated cardiac muscle tissues.
