About L-Carnitine
L-Carnitine is a small-molecule zwitterion with a molecular weight of 161.20 g/mol. Researchers have characterized it in the biochemical literature as the L-(–) enantiomer of carnitine, biosynthesized in mammals from the amino acids lysine and methionine [1]. The compound is described as the biologically active stereoisomer; its D-enantiomer and racemic mixtures are typically distinguished in analytical work. L-Carnitine is freely soluble in water and is supplied as a white to off-white crystalline powder.
Research Background
L-Carnitine has been referenced extensively in the published in vitro and animal-model literature on mitochondrial biology and the carnitine palmitoyl transferase (CPT) system. Investigators have characterized its role in the CPT-I/CPT-II shuttle in isolated mitochondrial preparations and in cell-culture systems used to study fatty acid β-oxidation pathways. Comparative studies in rodent models have examined endogenous carnitine biosynthesis, tissue distribution, and the activity of carnitine acyltransferases. The compound is also commonly employed as a reference standard in analytical chemistry method development for the quantification of carnitine and acylcarnitine species in biological matrices. These references describe findings in non-human models, isolated systems, and analytical contexts, and do not constitute claims about effects in humans.
