Abstract:
A method of making 1:1 complex salts of alpha amino acids and a metal ion which is either zinc or manganese, the method comprising reacting a water soluble zinc salt or manganese salt with an alpha amino acid in the presence of catalytically effective amount of ferric ion which aids in solubilizing the metal salt while simultaneously enhancing the formation of 1:1 complexes between the selected zinc or manganese salt and the desired alpha amino acid, particularly methionine.
