3. A mixture of amino acids can be separated by electrophoresis.
4. In both solid or aqueous solution, amino acids can exist as zwitterions depending on
the pH.
A zwitterion is a particle containing both a positive and negative ion.
It dissolves in water and has a high melting point as it is ionic.
Hence amino acid is less basic and is less acidic than a simple amine or a simple carboxylic
acid.
They are crystalline solid soluble in water.
