The term hydrophobic (hydro="water", phobic="fearing") is used to describe molecules that will not interact with water. Such molecules can also be known as lipophilic (fat-loving). Hydrophobic molecules are usually neutral and non-polar and so will not dissolve in polar solvents such as water[1]. Instead, hydrophobic molecules are inclined to group together to avoid associating with water[2]. This is a key feature in the phospholipid bilayers[3] of cell membranes. Examples of hydrophobic substances include fats, oils and alkanes.
Hydrophilic molecules are able to interact with water through hydrogen bonding[4].
