True or False An essential amino acid is one which is not synthesized in the body and thus must be supplied in our diet.  All amino acid contain carbon, hydrogen, oxygen, nitrogen and sulfur. Proline is the only common amino acid with a secondary amine. The pH at which there is no migration of an amino acid towards either electrode is called isoelectric point.
