The cell membrane primarily consists of lipids and proteins, with carbohydrates also playing a role. Phospholipids are the most plentiful of the lipids present with unique physical properties. Phospholipids are amphipathic, which presents both a hydrophilic heads and hydrophobic tails. Most membrane proteins are also amphipathic, with the hydrophilic region on the outside of the membrane (Campbell Biology, 2017). The cell membrane serves to facilitate required molecules in and out of the ce...
