Three model dipeptides containing a dehydroalanine residue ( AAla) at the C-terminal, Boc-X-AAla-NHCH3 [ X = Ala, Val, and Phe,] have been synthesized and their solution conformations investigated by 'H-NMR, IR, and CD spectroscopy. NMR studies on these peptides in CDCl, clearly indicate that the NH
Fourier transform ir spectra have been recorded for three 3 10 -helical and one ␣-helical pentapeptides containing dehydrophenylalanine, in a thin solid film, in order to find marker bands for various secondary structures encountered in peptides containing dehydroaminoacids. The peptide solutions we
