Amino acids have two functional groups -NH2 and -COOH.Hence the amino acids exists as a dipolar ion (or) zwitter ion.As a result strong eletrostatic forces exists between zwitter ions.hence amino acids have high melting & boiling points.
H2N-CH(R)-COOH <--------------> +H3N-CH(R)-COO-
amino acid zwitter ion
