lipid bilayer

The two layers of phospholipid molecules included within the outer membrane of most cells. These layers are arranged so their two hydrophilic (water-soluble) sides face the interior and the exterior of the cell, and their hydrophobic (nonpolar) core is in between. The membrane is relatively impermeable to molecules such as glucose and amino acids but very permeable to lipid-soluble molecules such as oxygen, carbon dioxide, and alcohol.

Herewith, we obtained the electron density profile of the polar head group, of the acyl chain regions of the lipid bilayers, and of the fraction of the resulting unilamellar vesicles (32,33) by using the function:

This study provides valuable data for characterizing the dynamical behaviour of lipid bilayers. The simplicity of the model allows for its application in studying various subjects such as lipid raft and more complicated cases where functional components are included in the membrane bilayer.

The two vesicle systems exhibit a similar scattering pattern with a broad peak in the q-range from 0.4 to 2 [nm.sup.-1], which can be attributed to the scattering of the lipid bilayers, known as a form factor of the bilayer.
