(1) (In Formula (1), R represents an alkyl group or an aryl group which may have a substituent. X is a group bonded to the N-terminus of Y, and represents —OCO—, —SONHCO—, —NHCO—, —NHCS—, or —SO—. Y represents an amino acid residue or a peptide residue. Z represents a group bonded to the C-terminus of Y and represents an OH group or an OR″ group. When Y is an amino acid residue other than a cystine residue or when Y is a peptide residue not having a cystine residue, m=1, and when Y is a peptide residue having n cystine residues, m=n+1 and n is 1 or 2.)
