Free and printable high-quality cell membrane diagrams are available for you to help your biology! The membrane is composed of a phospholipid bilayer arranged back-to-back. The membrane is also covered in places with cholesterol molecules and proteins. Check out the plasma membrane diagram below to see the detailed parts of the structure.
Shown above is the simplified version of a cell membrane diagram. Cell membranes contain a variety of biological molecules, notably lipids and proteins. Each cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. Phospholipids are a main component of the cell membrane. These are lipid molecules made up of a phosphate group head and two fatty acid tails. The properties of phospholipid molecules allow them to spontaneously form a double-layered membrane.
When in water or an aqueous solution, which includes the inside of the body, the hydrophilic heads of phospholipids will orient themselves to be on the outside, while the hydrophobic tails will be on the inside. The technical term for this double layer of phospholipids that forms the cell membrane is a phospholipid bilayer.
