The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures.

However, the effect of the cell membrane on the cellular endocytosis Furthermore, the differences in the composition of static protein corona between naked 

 Exhibits TRILAMINAR (3-layered) STRUCTURE i.e. two electron dense lines separated by an electron lucent central zone.  Each layer is 2.5nm thick. 4. Structure of Cell Membrane Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.

Depending on the membrane’s location and role in the body, lipids can make up anywhere from 20 to 80 percent of the membrane, with the remainder being proteins. Cell membrane can form different types of "supramembrane" structures such as caveola, postsynaptic density, podosome, invadopodium, focal adhesion, and different types of cell junctions. These structures are usually responsible for cell adhesion, communication, endocytosis and exocytosis. Cell membrane is a protective covering that acts as a barrier between the inner and outer environment of a cell (in animals).

Cell Membrane is present in all organisms including plants. The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include: Protecting the integrity of the interior cell.

12.2) (Ishihara et al., 1990).The synthesis of the MPC was difficult; however, in 1987, Ishihara considered a new process for its synthesis and … The cell membrane is a double layer of phospholipid molecules.
