Zinc deficiency is one of the serious problems of trace element nutrition in the world, which causes a series of pathologic effects. Based on the principles of bioinorganic chemistry, the ternary complexes of Zn-lysiue-histidine were studied as a substitution of zinc sulfate for zinc supplementation. It has also been proved by animal trail. Zinc deficiency is one of the serious problems of trace element nutrition in the world, which causes a series of pathologic effects.
