Recall that phospholipids have a hydrophobic end and a hydrophilic end and that when placed in water they will orient themselves accordingly (5.11 pg 79). This is the basis for the plasma membrane of a cell.The cell membrane consists of a phospholipid bilayer with embedded proteins.ecall that phospholipids have a hydrophobic end and a hydrophilic end and that when placed in water they will orient themselves accordingly (5.11 pg 79).

Figure 1: The lipid bilayer and the structure and composition of a glycerophospholipid molecule. (A) The plasma membrane of a cell is a bilayer of glycerophospholipid molecules. (B) A single glycerophospholipid molecule is composed of two major regions: a hydrophilic head (green) and hydrophobic tails (purple).(C) The subregions of a glycerophospholipid molecule; phosphatidylcholine is shown as an example.hey are often anchored in place within the membrane by tethers to proteins outside the cell, cytoskeletal elements inside the cell, or both. Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot.
