Keywords: Cell recognition; glycolipids; lyotropic cholesteric phase; helical twisting power (HTP)![]() Natural lipids are normally chiral. These chirality reduces the symmetry of membranes (-> in plane properties) and enhances the specifity of interactions. Glycolipids can be used as chiral dopants for lyotropic nematic phases. The helical twisting power in these cholesteric phases depends on the length of the sugar units and the conformation of the sugar. Conformation changes and aggregation process (recognition) changes the helical twisting power. We are characterizing the phase behaviour (thermotropic phases, lyotropic phases) and supramolecular structures (micelles, vesicles, gels) of glycolipids and measuring the interaction between carbohydrates and lipids in LC test phases. The goal is to quantify recognition processes based on weak molecular interactions. The long term goal is to influence recognition processes. Contact:
