Water is a small polar molecule made up of one oxygen atom covalently bonded to two H atoms while phospholipids are relatively a larger class of molecules made up of glycerol connecting two fatty acids and a phosphate group.
The phosphate group, along with the hydroxyl groups of glycerol, is structurally known as the polar head, as it gives the polar character to the phospholipid. The tail-like aliphatic fatty acids are largely nonpolar. These two opposing characters present in a single molecule give phospholipids an amphipathic nature: the polar head is hydrophilic while the nonpolar tail is hydrophobic.
Describe the structure characteristics of water and phospholipids. Include how these characteristics result in bilipid membrance formation. Mention the bonds and forces involved.
