Conformational preferences of alanine tripeptide in water, trifluoroethanol and dimethyl sulfoxide studied by vibrational spectroscopy
Alanine tripeptide is a good model molecule to analyze a conformational distribution of an unstructured peptide backbone, to study a competition between the intraand intermolecular hydrogen-bonding, as well as the favourable solvation conditions. In our work, we used three different spectroscopic techniques, the Raman and infrared (IR) spectroscopy, and the vibrational circular dichroism (VCD) ...

Role of solvent in determining conformational preferences of alanine dipeptide in water.
Evidence from a variety of spectroscopic probes indicates that (phi, psi) values corresponding to the left-handed polyproline II helix (P(II)) are preferred for short alanine-based peptides in water. On the basis of results from theoretical studies, it is believed that the observed preference is dictated by favorable peptide-solvent interactions, which are realized through formation of optimal ...
