Lipid bilayers are made up of

Lipid molecules found in cell membranes are amiphilic molecules, with one water-soluble end, and one hydrophobic end. The water-soluble end is usually charged, while the hydrophobic end is usually one or more hydrocarbon chains. The lipids found in cell membranes are mostly molecules with two hydrocarbon chains of about 10 carbons. Lipid bilayers are made up of phospholipids that have variable head groups and fatty acid chains.The lipid bilayer acts as a very good electrical insulator and has direct bearing on the way in which the proteins embedded in the lipid bilayer will behave.
