Statistical molecular model for hydrated peptides. Application to angiotensin II analogs.
A statistical molecular model for hydrated peptides is used to stimulate the behaviour of various peptide chains in aqueous solution. The reliability of the model is ascertained by the evolution of the characteristic ratio, Cn, for hydrophobic and hydrophilic polypeptide chains, such as, respectively, poly-Ala and poly-Ser. The comparison of computed and experimental properties related to non radiative energy transfer of angiotensin II analogs, assuming that an ensemble of conformers is a satisfactory representation of the state of these molecules in water, provides further support for the model.
