There are more than four elements in proteins : Carbon, hydrogen, oxygen, nitrogen, sulphur and selenium being the main six. It is not clear where you got the number 4 from and therefore which four you are asking about.
it is like what you do on a map
carbohydrates, lipids, proteins and nucleic acids
addition, subtraction, multiplication, and division.

There are four functions of proteins within the cell membrane. The four functions of proteins are active transport, cell recognition, cell communications, and are used as enzymes in the cell membrane.
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
proteins
Membrane proteins have a variety of functions. They relay signals between the cell's inside and outside environments. Transport proteins move the molecules across the membrane.
Most membrane functions are carried out by proteins. The cell membrane is important because it protects what is inside the cell from outside damage.
Receptors, Selective Channels and pores
Most of the active functions of plasma membranes are carried out by proteins.
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
Once the proteins are produced by the
The relative amounts of proteins and lipids
Proteins are not primary components of cell membrane. The proteins on the cell membrane have special functions, like receptors and transporters.
Membrane proteins relay signals between the cell's internal and external environments. They transport proteins and move molecules and ions across the membrane. They have many activities such as oxidoreductase, hydrolase or transferase.
