![]() ![]() Ī phospholipid is an amphipathic molecule, meaning it has both hydrophobic and hydrophilic elements. Phospholipid structure :ĬH 2 OH-CHOH-CH 2 OH is the chemical formula of phospholipid. This semi-permeable barrier prevents polar molecules from passing through, letting the cell regulate the concentration of different chemicals via protein channels. The surface can operate as a cellular membrane when the phospholipid molecules are linked by other lipids and integral proteins. The plasma membrane is made up of a bilayer of phospholipid molecules. A phospholipid is an amphiphilic molecule found in cell membranes that consists of a polar head region, a unit of glycerol, and two or more non-polar fatty acid tails. ![]()
