Question

Discuss zwitter-ion structure of amino acids.​

Answer 1

The physical properties of amino acids resemble ionic compounds rather than covalent compounds. they are crystalline solids with high M. pts. they are soluble in water and practically insoluble in alcohol,ether, etc. These facts lead to conclusion that amino acids exists as dipolar ion or zwitter-ion.

The zwitter-ion structure of amino acids is further supported by the following facts:-

(1) the dipole moments of amino acids are exceptionally high.

(2) The migration of amino acids in an electric field depends upon pH value of the solution.

(3) Raman spectra measurements also confirm the zwitter-ion structure of amino acids.
