The present invention relates to amino acids, complexes, and compounds comprising deuterium and tritium isotopes preferably alpha deuterated amino acids, polypeptides, antibodies, derivatives and saccharide-amino acid complexes and conjugates. In some embodiments, the invention relates to methods of using compounds comprising deuterium for imaging biochemical concentrations and distributions in mammalian tissues using nuclear magnetic resonance spectroscopy. In some embodiments, the invention relates to the used of said amino acids derivatives and complexes in boron neutron capture therapy. In some embodiments, the present invention relates to the preparation of amino acids, polypeptides, antibodies, derivatives and saccharide complexes/conjugates comprising heavy hydrogen isotopes. In some embodiments, the invention relates to racemizing amino acids starting from compositions of any optical purity. In further embodiments, the invention relates to the preparation of amino acids and their N-acyl counterparts with deuterium incorporated at the alpha carbon.
