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.
The opposite of hydrophobic is hydrophilic. Click here to read about hydrophilic molecules. Hydrophilic molecules are able to interact with water through hydrogen bonding[4].
