摘要：

We report results of a preliminary molecular dynamics study of a 1-palmitoyl-2-oleoylphosphatidyicholine (POPC) bilayer at low hydration (5% in weight). Our results suggest a gel phase structure where the oleic chain is bent recalling the crystalline oleic acid structure. We have also found a discontinuity in the volume/temperature curve which might be related to the gel to liquid crystal phase transition in POPC ((C) Societe francaise de biochimie et biologie moleculaire / Elsevier, Paris).
