A cell membrane is composed of proteins and lipids. The chemical composition of each membrane varies depending on the particular cell. The membrane architecture is that of a lipid bilayer. The lipids are amphipathic in that they have hydrophilic polar heads pointing out and the hydrophobic portion forming the core. Proteins are embedded in the bilayer. They may pass through the bilayer ( as transmembrane proteins), or they may be inserted at the cytoplasmic or exterior face.
