Asparatic acid, glutamic acid, alanine, glycine were in general featured by relatively high contents and the contents of proline, valine, and serine were also high, but the contents of the basic amino acids were low. The constituents of the amino acids composed of the protein in the exoskeletons of the crustacea were similar to those of amino acid patterns of elastin. The compositions of the amino acids in the three parts of the exoskeletons of the crustacea : The amino acids in the carapaces, abdomens and pleopods, and telsons of the exoskeletons, were also analyzed, and compared each other. In the hard carapaces the contents of asparatic acid, glutamic acid and proline were high, in the soft parts of the abdomens and telsons the contents of glycine and the basic amino acids were also relatively high.}, pages = {33--37}, title = {Constituents of the Amino Acids Composed of the Protein in the Exoskeletons of the Crustacea.}, volume = {22}, year = {1973} }
