L-carnitine is white crystal or white transparent fine powder, slightly special fishy smell. It is very soluble in water, ethanol, methanol, slightly soluble in acetone, insoluble in ether, benzene, trichloromethane, ethyl acetate. It is very easy to absorb moisture and will deliquesce or may even liquefy when exposed to air. It can be placed in the solution of pH 3~6 for more than 1 year, and can resist high temperature above 200℃, and its combination bond and binding group have good water solubility and water absorption.
L-carnitine is a compound with a variety of physiologically active functions. Its main function is to promote fatty acid β-oxidation; it can also regulate the acyl ratio in mitochondria and affect energy metabolism; L-carnitine can participate in the transport of branched-chain amino acid metabolites, thus promoting the normal metabolism of branched-chain amino acids. In addition, L-carnitine plays a role in the elimination and utilization of ketone bodies, acts as a biological antioxidant to scavenge free radicals, maintains the stability of membranes, and improves the immunity of animals as well as their ability to resist disease and stress.
