Description

Stearoyl-L-Carnitine is a high-purity, long-chain acylcarnitine derivative, a critical biochemical intermediate in cellular energy metabolism. This compound is essential for research and development in metabolic studies and pharmaceutical applications, offering a reliable standard for analytical and diagnostic purposes. It is primarily utilized by researchers in biochemistry, pharmaceutical scientists developing metabolic therapies, and manufacturers of in-vitro diagnostic kits.

Application

• Biochemical Research: Used as a reference standard and substrate in studies of fatty acid oxidation, mitochondrial function, and carnitine palmitoyltransferase (CPT) enzyme activity.
• Pharmaceutical Development: Serves as a key intermediate or analytical standard in the research of drugs targeting metabolic disorders, such as primary carnitine deficiency or other inborn errors of metabolism.
• Diagnostic Manufacturing: Employed in the production of calibrators, controls, and reagents for clinical diagnostic assays that measure acylcarnitine profiles, often via tandem mass spectrometry (MS/MS).
• Nutraceutical Research: Investigated for its potential role in lipid metabolism and energy production within advanced nutritional supplement formulations.
• Cell Culture & Metabolism Studies: Applied in in-vitro models to investigate the effects of specific acylcarnitines on cell signaling, insulin resistance, and metabolic pathways.
