| Research Abstract |
A highly sensitive and selective 2D-HPLC method for the simultaneous and enantioselective determination of all proteinogenic and clinically used amino acids has been established. The system was applied to various disease model animals and also to human clinical samples. As a result, the amount of D-Ser was higher in the spinal cord of ALS model mouse than that in the control mouse, and the usefulness of chiral amino acid metabolomics was also shown in the metabolic disorders of amino acids. In human plasma and urine, various D-amino acids such as D-Ser and D-Ala were observed, and further studies are in progress
