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.
