The chemical structures of the 20 standard amino acids at pH 7, along with their 3 and 1 letter codes, are givern in alphabetical order below. While the oxygen and nitrogen atoms of the peptide bonds may serve as a donor atom to complex a metal ion, very often the ligands for the metal come from the amino acid side chains. Takea few moments to examine the chemical structures of the different side chains. Circle the side chains that you...
