L-Carnitine 600mg/mL Peptide (≥99% Purity)
L-Carnitine is a naturally occurring amino acid derivative that plays a critical role in energy metabolism and mitochondrial function. The 600mg/mL concentration provides a high-potency research formulation suitable for laboratory investigations into fatty acid oxidation, cellular energy production, and metabolic pathways.
Chemically known as Levocarnitine or 3-hydroxy-4-N-trimethylaminobutyrate, L-carnitine is the biologically active stereoisomer responsible for the transport of long-chain fatty acids across the inner mitochondrial membrane for β-oxidation. Its name derives from the Latin word carnus (meat), reflecting its discovery in and presence within animal tissues.
Research has extensively investigated L-carnitine’s role in maintaining metabolic homeostasis, supporting cardiac function, and influencing energy balance. This product is designed for qualified researchers exploring mitochondrial dynamics, lipid metabolism, and therapeutic applications in controlled laboratory settings.
Mechanism of Action
L-Carnitine functions as an essential carrier molecule in cellular energy metabolism through multiple pathways:
Fatty Acid Transport:
-
Facilitates the translocation of activated long-chain fatty acids across the inner mitochondrial membrane
-
Converts fatty acids into acyl-carnitines for transport via carnitine palmitoyltransferase (CPT) system
-
Enables mitochondrial β-oxidation for ATP production
Metabolic Support:
-
Regulates the ratio of acyl-CoA to free CoA within mitochondria
-
Participates in removing toxic compounds from mitochondrial compartments
-
Involved in branched-chain amino acid metabolism
Cellular Protection:
-
Contributes to calcium influx regulation
-
Preserves endothelial integrity
-
Reduces oxidative stress and inflammation in research models
Key Research Applications:
-
Fatty acid metabolism and mitochondrial transport studies
-
Cardiovascular function and energy homeostasis research
-
Insulin sensitivity and metabolic disorder investigations
-
Neuroprotection and cognitive function research
-
Exercise physiology and recovery models

Research Background
Fatty Acid Metabolism
L-Carnitine is essential for mitochondrial transport of long-chain fatty acids. Clinical research in dialysis patients receiving 600mg/day oral L-carnitine demonstrated significant increases in total carnitine, free carnitine, and acylcarnitine serum concentrations. Studies have also shown improvements in hemoglobin levels and reductions in muscle cramping.
Metabolic Health
L-Carnitine has demonstrated potential in improving insulin sensitivity, with research indicating effectiveness in homeostasis model assessment of insulin resistance (HOMA-IR) scores. Lipid profile improvements have been observed including reduced total cholesterol, LDL cholesterol, and triglycerides.
Cardiovascular Research
Research has associated L-carnitine with cardioprotective effects through reduced oxidative stress, inflammation, and preservation of endothelial integrity. Studies indicate potential benefits in reducing ventricular arrhythmias and anginal symptoms.
