The Cell Membrane
Proteins embedded in the cell membrane.
There are proteins embedded in the membrane also. Some of these proteins exist on the aqueous side (outside) while others are only embedded on the inside. These are called peripheral membrane proteins. Some proteins go span the entire length of the lipid bilayer and are called transmembrane proteins. Peripheral membrane proteins are only temporarily attached and can become free by some types of stresses (i.e. detergents, solvents etc.). Integral membrane proteins are proteins that are permanently attached to the membrane.
There are two types of proteins that are embedded in phospholipid membranes, extrinsic and intrinsic. Extrinsic proteins are only partially embedded in the membrane. They aid the structural stability of the membrane and when in conjunction with glycolipids can be involved in cell recognition. Intrinsic proteins pass all the way through a membrane. Some of them may be channel proteins which act as passages through the membrane for some molecules and ions.
It is a lipid bilayer with proteins floating in it.
