Discard 30 DAYS after opening.Description & MechanismL-Carnitine is a naturally occurring small molecule involved in mitochondrial fatty acid metabolism. In biochemical and cellular research systems, L-Carnitine functions as a carrier molecule facilitating the transport of long-chain fatty acids across the inner mitochondrial membrane via the carnitine shuttle mechanism.Within experimental models, L-Carnitine participates in reversible esterification reactions with acyl-CoA derivatives, forming acylcarnitines that are translocated into the mitochondrial matrix for β-oxidation. This process is central to studies of cellular energy metabolism, mitochondrial function, and lipid handling under controlled laboratory conditions.L-Carnitine is widely used as a reference compound in metabolic research due to its well-characterised chemical structure, stability, and conserved biochemical role across species.Applications in ResearchAs a molecular tool for studying mitochondrial fatty acid transport mechanismsInvestigation of cellular energy metabolism and β-oxidation pathwaysUse as a reference compound in metabolic, enzymatic, and transporter assaysIn vitro and ex vivo studies examining acylcarnitine formation and turnoverHandling & StabilityStore in a cool dark place.
