Let's review. Phospholipids are a type of lipid-one of the four main classes of molecules that make up living things. Phospholipids serve a very important function by surrounding and protecting internal cell components.
Most phospholipids contain a âdiglycerideâ, a phosphate group and a simple organic molecule such as choline, which is a water-soluble essential nutrient. In water based solution, the phospholipids automatically arrange themselves into a double layer, or as a âphospholipid bi layerâ.The fatty acids, which repel water, are found in the middle of the bi layer.n water based solution, the phospholipids automatically arrange themselves into a double layer, or as a âphospholipid bi layerâ.
