Abstract: The influence of chirality on the structure of high- and low-temperature phases of monoglyceride monolayers has been studied by Brewster angle microscopy (BAM) and grazing incidence X-ray diffraction (GID). While there is no effect of the chiral center of monopalmitoylglycerol on the monolayer structure at 20 °C, an influence of chirality has been found for monostearoylglycerol at 5 °C. At low temperature the latter compound has an oblique lattice of the molecule chains at all investigated surface pressures, while the racemic mixture exhibits a rectangular structure. Additionally, it can clearly be visualized by BAM that the racemic mixture exhibits a phase transition between 6 and 12 mN/m at 5 °C characterized by a change of the tilt azimuth. By using GID, this transition could be identified as a change of the azimuthal tilt angle from a nearest neighbor (NN) direction to a next nearest neighbor direction (NNN).
