Levocarnitine
L-Carnitine
L-Carnitine (levocarnitine) is a quaternary ammonium compound biosynthesized from lysine and methionine, essential for the transport of long-chain fatty acids across the inner mitochondrial membrane for beta-oxidation. Research has studied its roles in energy metabolism, cardiac function, skeletal muscle performance, and neuroprotection. It is used as a reference compound and research tool in metabolic, cardiovascular, and aging studies.
