Definitions:

Hydrophilic Region

A part of a molecule that has affinity for water and can form hydrogen bonds with water molecules.

Hydrophobic Region

A part of a molecule that is repelled by water and typically soluble in nonpolar solvents.

Hydrogen Bond

A weak bond formed between a hydrogen atom in one molecule and an electronegative atom, such as oxygen or nitrogen, in another molecule, important in the structure of water and biological molecules.

Polar Covalent Bond

A type of chemical bond where a pair of electrons is unequally shared between two atoms.
