L-Carnitine is a naturally occurring quaternary ammonium compound involved in the intracellular transport of long-chain fatty acids into the mitochondrial matrix for beta-oxidation. It has been studied extensively in metabolic and exercise physiology research for its relationship to fatty acid utilization, mitochondrial energy production, and recovery-associated metabolic pathways. Its role as a carrier molecule within mitochondrial transport systems makes it foundational to cellular energy metabolism research across multiple physiologic contexts. Sterile solution, 10mL vial at 100mg/mL. For research use only.
