Absolute Configuration of the Naturally Occurring α Amino-Acids

THANKS largely to the extensive researches of Levene and his collaborators, it now appears to be well established that, as suggested by Clough in 1918 1, the naturally occurring α amino-acids all ...

Determination of sequence and absolute configuration of peptide amino acids by HPLC–MS/CD-based detection of liberated N-terminus phenylthiohydantoin amino acids

We report a method for the simultaneous determination of the sequence and absolute configuration of peptide amino acids using a combination of Edman degradation and HPLC–MS/CD. Phenylthiohydantoin ...
