[High performance liquid chromatography of peptide bioregulators, their fragments and derivatives. III. Regularities of sorption, prediction of retention and analysis of peptides by a reversed phase HPLC method].

Parameters of statistical models of fully or partially protected peptides' retention on Zorbax ODS and Silasorb C18 have been compared. The proposed model can be used for non-protected linear and cyclic peptides. Special increments have to be introduced in calculation of hydrophobicity of these peptides.
