Let's review. Phospholipids are a type of lipid-one of the four main classes of molecules that make up living things. Phospholipids serve a very important function by surrounding and protecting internal cell components.
These specific properties allow phospholipids to play an important role in the phospholipid bilayer. In biological systems, the phospholipids often occur with other molecules (e.g., proteins, glycolipids, sterols) in a bilayer such as a cell membrane.
