Abstract

Recently, chiral glycolipids with unsaturated hydrocarbon chains proved to self-assemble in water to form nanotubes. We investigated the phase transition behavior of a glycolipid in tube-forming process by using ultra sensitive differential scanning calorimetry (DSC) and circular dichroism (CD) with in-situ measurement. Our experimental results showed that the tube-forming process occurred in several hours and the phase transition from vesicles (liquid crystalline phase) to tubes (gel phase) followed two steps with decreasing temperature. We also found that the glycolipid nanotubes appearing in low temperature region were in a glassy state ascribable to reducing freedom of molecular motion of the glycolipid.
