We have performed a 500 ns Molecular Dynamics (MD) to study the lamellar phase of lyotropic liquid crystasl consisting of more or less hydrophobic lamellas. As more hydrophobic lamellas were used lamellas of biological origin, in this case, asymmetric human erythrocyte membrane and as less hydrophobic lamellas-planar micelles of sodium pentadecylsulfonate (SPDS), representing a commercial interest. Some important parameters have been obtained which characterize the dynamic structure of lyotropic liquid crystal's lamella. A good correspondence is established for the results of computer and physical experiments.
