In biological systems, ionic interactions, in which oppositely charged ions attract each other strongly, may serve as intermolecular or intramolecular forces. In some cases, these may involve metal cations, such as , or anions, such as . In many cases, the cation is an ammonium ion from an amino group, such as ; the anion may be from a carboxylic acid, such as .

In nonbiological systems, such interactions are commonly referred to as ionic bonding.
