Proteins many times line the outer surface of cells. These are used in diffusion and also provide support for the cell.
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. Peripheral proteins are not bonded as strongly to the membrane. They may just sit on the surface of the membrane, anchored with a few hydrogen (H) bonds.
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.

Inner membrane proteins are embedded in the inner membrane of bacteria, while outer membrane proteins are located in the outer membrane. To obtain membrane proteins from E. coli, you can disrupt the cells through methods like sonication or French press, followed by using differential centrifugation to separate the inner and outer membrane fractions based on their densities. Further purification techniques such as density gradient ultracentrifugation or membrane solubilization can be used to isolate inner and outer membrane proteins specifically.

A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.

Both the inner and outer leaflets of the plasma membrane in a cell have intrinsic and extrinsic protein molecules embedded within the phospholipid bilayer. Intrinsic proteins are integral membrane proteins that span the membrane, while extrinsic proteins are peripheral membrane proteins that are attached to the surface of the membrane.
integrai Essential or necessary for completeness; constituent ... and peripheral is Related to, located in, or constituting an outer boundary or periphery.
