| Outline of Final Research Achievements |
By using chiral amino acid analysis discriminating the enantiomers, highly sensitive and selective analytical methods have been designed and applied to various animal models. Chiral amino acid profiles sometimes drastically change in the tissues and physiological fluids under disease conditions. In the present study, various metabolic related amino acids were selected as the analytical targets, and enantioselective multi-dimensional HPLC systems have been developed for the diagnosis of the metabolic disorders of aromatic amino acids, branched aliphatic amino acids, sulfur-containing amino acids and urea cycle. As a result, target amino acid enantiomers could be determined without severe interference in the plasma and urine, and possible biomarkers were found.
