This paper analyses the behavior of fatty acid-cholesterol mixtures, components of biological membranes, under the influence of the electromagnetic filed. The mixtures acid lauric-cholesterol, prepared in this layers of 24 micrometers , have a liquid crystal behavior at room temperature. Spectra obtained in the range (330 divided by 800) nm put into evidence some regions of resonance between the oscillatory system characterizing the textures and the electromagnetic field. The result are discussed in terms of Maxwell's formalism. A good agreement between experiment and theory was obtained for the lauric acid. The impurification with cholesterol leads to a greater disorder in the system and the agreement with the theory is no more satisfactory.
