hydrophilic - having a strong affinity for water; tending to dissolve in, mix with, or be wetted by water. chemical science, chemistry - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions.
Hydrophilic molecules (and portions of molecules) can be contrasted with hydrophobic molecules (and portions of molecules). In some cases, both hydrophilic and hydrophobic properties occur in a single molecule. An example of these amphiphilic molecules is the lipids that comprise the cell membrane.nother example is soap, which has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively.
