Malonyl-L-carnitine-d3 Trifluoroacetate (CAS 910825-21-7 (unlabeled))

Malonyl-L-carnitine-d3 Trifluoroacetate is a specialized derivative of L-carnitine. L-carnitine is a naturally occurring compound involved in the transport of fatty acids into mitochondria, where they are oxidized for energy production.The malonyl group addition to L-carnitine creates a derivative that can be involved in or mimic specific metabolic pathways, potentially influencing fatty acid metabolism and energy production. The trifluoroacetate salt form enhances the compound′s solubility in organic solvents and water, facilitating its handling and application in experimental setups. In stable isotope labeling, Malonyl-L-carnitine-d3 Trifluoroacetate can be used as an internal standard or tracer to quantify L-carnitine and its derivatives in biological samples with high accuracy. This is particularly valuable in mass spectrometry-based assays, where the deuterium-labeled compound can be distinguished from its unlabeled counterpart based on mass differences, allowing for detailed metabolic profiling.
