Write short notes on: Zwitter ion.
- A zwitterion is a molecule that has at least two functional groups: one having a positive charge and the other having a negative charge, with an overall charge of zero. Zwitterions can form from other molecules called ampholytes, or amphoteric compounds and can act as both an acid and a base.
- Zwitterions are polyelectrolytes that contain both positively and negatively charged groups, and the overall charges are neutral.
