Abstract
The conformation of cyclolinopeptide A [cโ(ProโProโPheโPheโLeuโIleโIleโLeuโVal)], a naturally occurring peptide with remarkable cytoprotective activity, has been investigated by means of molecular dynamics simulations in various molecular environments. Structural and dynamical properties have been analyzed and compared with those experimentally determined. A detailed analysis of hydrogen bonds is reported.

## Synopsis Cyclolinopeptide A, a cyclic nonapeptide isolated from linseed, has lately attracted large interest for i t s cytoprotective activity. The recent elucidation of its solid state structure has prompted us to undertake a detailed conformational analysis in solution. Room-temperature 'H-nm
This article describes the collisional dynamics (CD) method adapted for molecules with geometrical constraints within a description using Cartesian coordinates for the atoms. In the CD method, stochastic collisions with virtual particles are included in usual molecular dynamics simulations to couple
