Used in research related to fatty acid metabolism, particularly in studies involving carnitine palmitoyltransferase (CPT) enzymes, which play a key role in transporting long-chain fatty acids into mitochondria for energy production. Serves as a substrate to investigate enzyme kinetics and inhibition mechanisms in metabolic disorders. Also utilized in cellular and biochemical assays to modulate acyl-carnitine levels, helping to assess mitochondrial function and metabolic flux in tissues such as muscle and liver. Investigated in models of insulin resistance and type 2 diabetes to understand lipid-induced metabolic impairments.
