Phospholipids
Phospholipids make up the majority of the bilayer that forms cell membranes. These phospholipids have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to form a stable barrier in the cell membrane. Other lipids, such as cholesterol and glycolipids, also play a role in the structure and function of cell membranes.
Phospholipid molecules form the two layers of the cell membrane. These molecules have a hydrophobic (water-repelling) tail and a hydrophilic (water-attracting) head, which arrange themselves into a double layer to create the lipid bilayer of the membrane.

A phospholipid bilayer.
Phospholipid molecules form the two layers of the cell membrane. These molecules have a hydrophobic (water-repelling) tail and a hydrophilic (water-attracting) head, which arrange themselves into a double layer to create the lipid bilayer of the membrane.
The lipid bilayer makes up the membrane of a cell. The lipid bilayer consists of opposing phospholipids, where the polar ends of both the top layer and the bottom layer of phospholipids face opposite directions.

Phospholipids are the primary type of molecule that forms the cell membrane. They have hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails, allowing them to arrange in a bilayer to create the cell membrane.
The main molecules are lipids (with different fatty acid chains depending upon the kind of membrane), proteins (that can be associated with the external part of the lipid bilayer, embedded in the lipid bilayer and those associated with the interior part of it ), and sugars (complex polysaccharides that can be part of the docking site of protein receptors, to have function of blood types, or to be recognized by antibodies).
Phospholipids, where one end is hydrophobic and the other is hydrophilic.
The cell membrane is a phospholipid bilayer, consisting of two layers of phospholipid molecules. Each phospholipid molecule has a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, creating a barrier that controls the movement of molecules in and out of the cell.
the cell membrane is composed of carbohydrates, proteins, and phospholipids. The proteins act as transport molecules to move material in and out of the cell (kind of like a tunnel). They are embedded in the membrane. These proteins are needed due to the phospholipid bilayer. The inside of the bilayer repels water, so this keeps all materials out of the cell unless it has been selected to be carried in by the proteins. The carbohydrates are located on the outside of the membrane. They recognize things the cell may need. For instance, ADH (Anti-diuretic hormone) is only needed in the kidneys, so the carbohydrates only recognize it there.
