Models for the conformational behaviour of angiotensin-II in acidic aqueous solutions

Clustering analysis is applied to a sample of Angiotensin-II conformations obtained from a Monte-Carlo procedure. It is shown that 5 families of conformations can describe entirely the sample. Each family can be represented by a typical conformer. Two of these last models are predominant in the description of Angiotensin-II in acidic solutions. These theoretical models are in agreement with recent experimental results.
