On the Lipid Composition of Membranes

Protoplasma, 1967
The lipid content of membrane preparations isolated from different origins has been demonstrated to vary from 30% to 75% on a dry weight basis. Depending on the procedure utilized for the preparation of red cell ghosts, this membrane was found to contain either 30% or 50% lipids, cholesterol and phospholipids, which together account for over 80% of the

Composite membranes for water desalination

PERSPEKTIVNYE MATERIALY
Methods of coatings forming on the surface of a poly(ethylene terephthalate) track-etched membrane by magnetron and electron-beam sputter deposition of polytetrafluoroethylene in vacuum are considered. It is established that the involve of these modification methods leads to the formation of composite membranes consisting of two layers, one of which is

On the Asymmetric Composition of Plasma Membranes

1977
By intuition, we always have known that there was asymmetry in the function and composition of plasma membranes. After all, we had to accommodate into that structure specific ion channels, pumps, transporters, receptors and many other functions which clearly demand highly differentiated molecular assemblies.
