What is a zwitterion?
A zwitterion is a neutral molecule that is formed by the interactions between an acidic COOH group and basic NH2 group on an amino acid, the positive and negative chanrges cancel each other out resulting in a molecule with no overall charge.

What is the isoelectric point?
This is ph value at which an amino acid exists as a zwitterion
