Abstract
The invention provides a peptide for complexing zinc ion, complex thereof and use therefor. The amino acid composition and sequence of the peptide for complexing zinc ion are Lys-Tyr-Lys-Arg-Gln-Arg-Trp (SEQ ID NO: 1). The peptide for complexing is derived from soybean or peanut, is an inherent component of foods, and has a super strong complexing effect with zinc ions.
