The material on optical modelling of pretransition processes in liquid crystalline hydrated lipid phases is presented. Results of estimation of the model of monoclinic phase formation are in the poorer agreement with X-ray diffraction data than the model of kinks appearance in the aliphatic core of layers. Arguments are presented in favour of complicated character of molecular rearrangements in lipid-water phases in the pretransition region and impossibility at present to correlate structural and calorimetric data when estimating premelting phenomena.
