Membrane lipid composition defines membrane protein spectrum
Trends in Microbiology, 2023In addition to glycerophospholipids, bacterial membranes often include amino acid-containing acyloxyacyl lipids. The functional implications of these aminolipids are largely unknown. However, a recent study by Stirrup et al. expands our understanding and shows that they are major determinants for membrane properties and the relative abundance of ...

Composite Membrane Estradiol Implant
Journal of Pharmaceutical Sciences, 1975The diffusion and permeability of large organic molecules through polymeric films were investigated, specifically the passage of estrogen through films of polyethylene, silicone, or a composite of these two films. Such systems are of interest because of the possibility of constructing a biocompatible implant that releases a hormone at a controlled and ...

Membrane distillation by novel hydrogel composite membranes
Journal of Membrane Science, 2016Novel polyelectrolyte hydrogel composites are developed by UV-initiated graft polymerization of acrylic acid and 2-hydroxyethyl methacrylate (functional monomers) and ethylene glycol dimethacrylate (cross-linker), on polypropylene flat sheet membranes (support).

Polyurethane Composite Membranes
Materials Science Forum, 2014Fibrous nanostructured polyurethane composite membranes were developed using electrospinning process. Membranes of polyurethane having silver and zinc oxide as additives were prepared by electrospinning of solutions having dimethylformamide (DMF) or its mixture with tetrahydrofuran (THF) (50:50 volume ratio) as solvent.

The invention relates to a composite membrane comprising a sinter metal support (1) and a membrane layer (3) disposed on said support or on at least one intermediate layer (2). According to the invention, the sinter metal support (1) is provided with an anticorrosion material in order to increase the long-term stability of the composite membrane.

Lipid Composition of Membrane Domains
2004The isolation of subfractions of cell membranes on the basis of their solubility in non-ionic detergents has led to the discovery of lipid domain structure in membranes. Detergents used for this purpose include Triton, Brij, Lubrol and CHAPS. Different lipid constituents are known to resist solubilization by different detergents and the resulting ...

Cell membranes—Composition: Structure: Function
Journal of Theoretical Biology, 1967Abstract Cell membranes are structures which form boundary layers between two cellular compartments. Membranes play an extraordinarily important part in the metabolism of cells. In some cells as much as 80% of the dry weight is localized within membranes.

The Composition of Biological Membranes
Archives of Internal Medicine, 1972The main components of biological membranes are proteins, lipids, and carbohydrates in variable proportions. Carbohydrates account for less than 10% of the mass of most membranes and are generally bound either to the lipid or protein components. Myelin has few functions and is made up almost entirely of lipids.
