## Abstract Isolated β‐hairpins in water have a temperature dependence of their conformational stability qualitatively resembling that of globular proteins, showing both cold and hot unfolding transitions. It is shown that a molecular‐level rationalization of this cold unfolding can be provided ext
Molecular dynamics simulations of -hairpin folding have been carried out with a solvent-referenced potential at 274 K. The model peptide V 4 D PGV 4 formed stable -hairpin conformations and the -hairpin ratio calculated by the DSSP algorithm was about 56% in the 50-ns simulation. Folding into -h
