, in its (1) normal (unionized) and (2) zwitterionic forms.]] A zwitterion (from and usually have a high solubility in water and a poor solubility in most Organic Solvent s. Ampholytes are molecules that contain both Acid ic and Basic groups (and are therefore Amphoteric ) and will exist as zwitterions at a certain PH . This pH is known as the molecule's Isoelectric Point . Ampholytic molecules make good Buffer Solution s — they resist change to the pH of a solution by selective ionization. In the presence of acids, they will accept the hydrogen ions, removing them from the solution. In the presence of Bases , they will donate hydrogen ions to the solution, again balancing the pH. Typical examples of zwitterions are:
Less common examples of zwitterions are:
