Peptide
 A peptide is disclosed which is represented by the formula: EQU H-X-Gly-Trp-Lys-His-Trp-Val-Tyr-Tyr-Thr-Cys-Cys-Pro-Asp-Thr-Pro-Tyr-Leu-Asp -Y -Z wherein one of X and Y stands for a single bond, an amino acid residue selected from the class consisting of Asp, Glu, Lys and a divalent group represented by the formula, ##STR1## (wherein n stands for an integer in the range of 1 to 17), or a peptide residue formed by peptide linkage of two to ten amino acid residues of at least one species selected from the class mentioned above, the other of X and Y stands for an amino acid residue selected from the class consisting of Asp, Glu, Lys and a divalent group represented by the formula, ##STR2## (wherein n stands for an integer in the range of 1 to 17), or a peptide residue formed by peptide linkage of two to ten amino acid residues of at least one species selected from the class mentioned above and Z stands for a hydroxyl group or an amino group, and two cysteinyl mercapto groups in the Cys-Cys moiety may be interlinked to each other to form a disulfide bond.
