  2. Lipid bilayer - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer

    The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells . The cell membranes of almost all organisms and many viruses are made of a lipid bilayer, as are the nuclear membrane surrounding the cell nucleus , and ...

  3. Phospholipid - Wikipedia

    en.wikipedia.org/wiki/Phospholipid

    Phospholipid bilayers are the main structural component of the cell membranes. In biological membranes, the phospholipids often occur with other molecules (e.g., proteins , glycolipids , sterols ) in a bilayer such as a cell membrane . [ 7 ]

  4. Fluid mosaic model - Wikipedia

    en.wikipedia.org/wiki/Fluid_mosaic_model

    Fluid mosaic model of a cell membrane. The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.

    For example the 'phospholipid bilayer' could refer to the height or depth dimension (corner to corner is the only dimension that fits visually). The dimension line should not be at an angle. It may be better to stick to Transport, Integral, Globular, Peripheral and Surface proteins (or similar classification) in the image and make finer ...

  6. Membrane lipid - Wikipedia

    en.wikipedia.org/wiki/Membrane_lipid

    Non-bilayer forming lipid like monogalactosyl diglyceride (MGDG) predominates the bulk lipids in thylakoid membranes, which when hydrated alone, forms reverse hexagonal cylindrical phase. However, in combination with other lipids and carotenoids / chlorophylls of thylakoid membranes, they too conform together as lipid bilayers.

  7. Cell membrane - Wikipedia

    en.wikipedia.org/wiki/Cell_membrane

    Illustration of a eukaryotic cell membrane Comparison of a eukaryotic vs. a prokaryotic cell membrane. The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates and protects the interior of a cell from the outside environment (the extracellular space).

  8. Lipid bilayer characterization - Wikipedia

    en.wikipedia.org/wiki/Lipid_bilayer_characterization

    Lipid bilayer characterization is the use of various optical, chemical and physical probing methods to study the properties of lipid bilayers. Many of these techniques are elaborate and require expensive equipment because the fundamental nature of the lipid bilayer makes it a very difficult structure to study.

  9. Biological membrane - Wikipedia

    en.wikipedia.org/wiki/Biological_membrane

    Phospholipid bilayers contain different proteins. These membrane proteins have various functions and characteristics and catalyze different chemical reactions. Integral proteins span the membranes with different domains on either side. [6] Integral proteins hold strong association with the lipid bilayer and cannot easily become detached. [9]
