They must be fat soluble so they can be in contact with the hydrophobic tails of the phospholipid bilayer.
The plasma membrane is made of phospholipids. Phospholipids contain a hydrophillic head group which is considered water soluable. They also contain a hydrophobic tail group whichi s considered lipid soluable
There are three classes of membrane transport proteins that permit water and solutes to bypass the lipid portion of the cell membrane. They are uniporters, symporters, and antiporters.
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
These are proteins that are permanently attached to or in the cell membrane via its hydrophobic domains interacting with the membrane's phospholipids.
the proteins that protrude from both surfaces of the bilayer

a cell membrane is a lipid bi-layer made of phospholipids and water
Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
Surprisingly, membrane proteins are found in or attached to the membrane.

water

yes it is soluable in water because it is found in sea water two please message me if you think im wrong :)
the proteins that protrude from both surfaces of the bilayer
Membranes bound within the cell membrane. Integral proteins extend from one side of the membrane to the other.
