20 Ιουν 2024 · Moreover, our whole-cell modeling suggests that all soluble (globular) proteins inside cells are surrounded by, on average, one full molecular layer (about 2.6 Angstrom) of biointerfacial...
1 Ιουλ 2019 · The localization of water molecules and hydration properties within membranes depend on both the lipid head group type and the organization of hydrocarbon acyl chains (e.g., gel, liquid-crystalline phase).
1 Ιουν 2014 · A cell membrane is not a lamellar phase, but a real object whose structure corresponds more or less to a lamellar phase. For the same token a bacterial toxin does not insert into the membrane through a nonlamellar phase, nor two membranes fuse via a rhombohedral phase.
9 Δεκ 2019 · Here authors present molecular dynamics simulations and EPR experiments to monitor permeation of oxygen and water through membranes in the liquid ordered and liquid disordered phases.
16 Οκτ 2001 · One of the simplest of these proteins transports water. Direct diffusion of water through the lipid bilayer is probably sufficient to supply the needs of many cells for water. However, for cells such as epithelial and endothelial cells involved in secretion and absorption, a high, regulated water supply is required.
The cell membrane is exposed to water mixed with electrolytes and other materials on the outside and the inside of the cell. When cellular membranes form, phospholipids assemble into two layers because of these hydrophilic and hydrophobic properties.
Cell Membrane: Structure and Physical Properties The cell membrane (or plasma membrane) is a thin closed sheet that fulfils a double role: (a) morphological – delimitates the cell from its external microenvironment and confines all of its subcellular organelles; (b) functional – regulates the exchange
