A biological membrane can be described as a membrane which encloses a cell. It separates a cell from the outer environment.
The main components of a biological membrane include proteins, lipids and carbohydrates. The carbohydrates either attach to lipids forming glycolipids or they attach to proteins forming glycoproteins.
The structure of a biological membrane constitutes of phosphate heads and tails which are made of fatty acids. The membrane contains a phospholipid bilayer.
