Abstract

Conformational properties of two potentially &bgr;-turn forming peptides were determined using a strategy which combines MD simulations, IR and VCD spectroscopy and quantum chemical calculations. This strategy could be a useful alternative for solution conformational analysis of short flexible peptides and could help to identify VCD features which are as yet unknown.
