lipid bilayer

[¦lip·id ′bī‚lā·ər]
(cell and molecular biology)
The foundational structure of plasma membranes; it is composed of two layers of phospholipids positioned such that their polar hydrophilic heads face outward and their nonpolar hydrophobic tails are directed inward, blocking entry of water and water-soluble material into the cell.

An additional feature of the lipid bilayer is that it has a highly positively charged quaternary ammonium (QA) ion as its terminal group.
Surface energies of supported lipid bilayers, optionally covered by PEG, were quantified with contact angle goniometry and AFM.
We began by asking a simple question in basic science: How does a water-soluble protein secreted by the bacterium Staphylococcus aureus penetrate and assemble itself in the lipid bilayer of a cell?
Addition of the lipid bilayer was performed by incubation of the polyelectrolyte-coated beads [last layer PAH (positively charged) in 0.
The basic building block of cellular and organelle membranes is the lipid bilayer, within which are embedded proteins of various shapes and traits.
The drug functions as an antioxidant, binding to the lipid bilayer of a cell membrane and serving as a protective agent.
We recently developed a new form of artificial lipid bilayer that in addition to exceptional stability, and simple reconstitution of membrane proteins, is capable of single-molecule fluorescence imaging and single-channel electrical recording with gigaohm seals.
These proteins float about slowly in the lipid bilayer.
To achieve this goal we have assembled a highly interdisciplinary team of leading groups all having synergies in their established research interests in the field of lipid bilayer nano-objects interactions.
Receptos also published the determination of a high resolution S1P1 receptor in Science on February 16, 2012, which revealed an enclosed binding pocket and a potential ligand entry route through the lipid bilayer.
The oily, or hydrophobic, ends formt the interior of the lipid bilayer by bunching together to avoid contact with the watery environments inside and outside the cells.
By suspending varying mixtures of those phospholipids in saline solution, the researchers made liposomes -- spherical compartments surrounded by a lipid bilayer -- and later used them to assess membrane damage.
