Ion chromatogram (lower) and CD absorption chromatogram (upper) of the PTH derivatives of acid hydrolysates of (a) the commercial pentapeptide l-Tyr-d-Trp-l-Ala-l-Trp-d-Phe and (b) the residual peptide l-Ala-l-Trp-d-Phe after elimination of l-Tyr and d-Trp by Edman reactions. The unit of CD absorption is mdeg.
