Lkt Laboratories CAS 208-768-0, ≥98%, Endogenous quaternary ammonium required for fatty acid transport. Improves biomarkers of exercise stress and increases bone mineral density.
L-Carnitine is an endogenous quaternary ammonium compound required for fatty acid transport; it is often given as a dietary supplement. The L-isomer is active, exhibiting anti-osteoporotic, antioxidative, and cardioprotective activities. In a clinical setting, L-carnitine administration increases muscle carnitine content and work output while decreasing glycogen utilization during exercise. Additionally, L-carnitine improves postprandial flow-mediated dilation, slightly increasing vascular function. In animal models, L-carnitine increases bone mineral density and decreases bone resorption. L-Carnitine also improves plasma markers of exercise stress such as malondialdehyde. L-Carnitine improves symptoms of cardiovascular disease accompanying myocardial infarction and decreases ventricular arrhythmias, symptoms of angina, and mortality rates.
Medchemexpress LLC L-Carnitine | 541-15-1 | 100.0% | 25 G
L-Carnitine ((R)-Carnitine) is a highly polar, small zwitterion that serves as an essential co-factor for the mitochondrial β-oxidation pathway. It functions by transporting long-chain fatty acyl-CoAs into the mitochondria for degradation. Additionally, L-Carnitine acts as an antioxidant and can ameliorate metabolic imbalances in various inborn errors of metabolism.
