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.

While the former technique allows spatiotemporal analyses (morphology, local curvature, and hydration) of the specific phases existing in the lipid bilayer, the last two techniques, respectively, allowed inquiring effects caused by artepillin C in the thermotropic lipid phase transition and changes in the structural properties of the model membranes at equilibrium conditions.
Band 3, the red cell anion exchanger 1 (AE1), passes through the lipid bilayer 14 times.
In Gram-positive bacteria, the cell wall susceptible to lysozyme is at the surface of the microorganism with lipid bilayers susceptible to ProteCoat underneath, while the reverse configuration exists in Gram-negative bacteria.

This property prevented them forming a lipid bilayer for W/O/W emulsion in the second stage and dispersal like micelles.
By its nonpolar nature, the SQ is located on the hydrophobic center of the lipid bilayer, organized in a spiral or extended conformation, oriented in parallel to the phospholipid chains between the cell membrane (Figure 2) [20].

At this point, we investigate the energy behavior of the molecular interaction energy of a lipid bilayer and a DNA molecule, by determining the penetration behavior of the ssDNA and dsDNA molecules through an assumed circular gap of radius b in the bilayer.

The motors, only about a nanometer wide, can be designed to target and then either tunnel through a cell's lipid bilayer membrane to deliver drugs or other payloads or disrupt the 8-10 nanometer-wide membrane, thereby killing the cell.
Nanopore-based DNA sequencing has been explored since the 1990s, when it was discovered that single-stranded DNA could be driven across a lipid bilayer through [alpha]-hemolysin pores (2).
For liposome with tetraether lipids, only complete vesicles and no fracture planes were visible in Cryo-SEM, indicating the tight packaging of tetraether lipids within the lipid bilayer.
