Vashchenko O. Physical properties of liquid crystalline models of biomembranes

: Мodel biopogical membranes. Сlarifying the influence of membranotropic agents on supramoleculrar ordering of biomembrahes. The methodes used were differential scanning calorimetry, optical spectroscopy, gravimetry. Data were obtained on the changes of phase transition parameters of model phospholipid membranes and helical pitch of cholesteric liquid crystals under the influence of wide range of biomolecules. Temperature dependences of UV absorbance spectra proved to be fit for observing the effects related to the changes in supramolecular structure of the systems. UV-induced changes in the color of liquid crystalline systems containing vitamin D isomers were observed. Fields of application are membrane biophysics, molecular biophysics.
