The phosphate group forms the hydrophilic head while the fatty acids form the hydrophobic tails. Provides a flexible matrix and a permeable barrier. Transmembrane Proteins – collection of proteins that float on or in the lipid bilayer. Provide passageways for substances and information into the cell.
