ionizable
Able to charge
Ionizable describes a substance capable of forming ions—atoms or molecules with an electric charge.
In chemistry, ionizable compounds can gain or lose electrons when dissolved or exposed to certain conditions: ionizable amino acids, ionizable functional groups.
The term appears frequently in discussions of drug absorption, since ionizable drugs behave differently at various pH levels.
