Chemical Information
FooDB NameAcetyl-L-carnitine
DescriptionL-Acetylcarnitine, also known as alcar or branigen, belongs to the class of organic compounds known as acyl carnitines. These are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. Thus, L-acetylcarnitine is considered to be a fatty ester lipid molecule. L-Acetylcarnitine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
