FERRIC ION CATALYZED COMPLEXATION OF ZINC AND/OR MANGANESE WITH ALPHA AMINO ACIDS

摘要

ABSTRACT OF THE DISCLOSUREA method of making 1:1 complex salts of alpha amino acidsand a metal ion which is either zinc or manganese, having the use-ful feature of being highly body absorbable nutritional supple-ments, the method comprising reacting a water soluble zinc saltor manganese salt with an alpha amino acid in the presence ofcatalytically effective amount of ferric ion which aids insolubilizing the metal salt while simultaneously enhancing theformation of 1:1 complexes between the selected zinc or manganesesalt and the desired alpha amino acid, particularly methionine.
