  • Patent number: 10753911
    Abstract: A chiral analysis method of a bound amino acid includes a step of hydrolyzing a bound amino acid using a deuterium chloride-deuterium oxide solution and/or deuterium oxide; a step of separating, by chiral separation, a D-form and an L-form of an amino acid generated by the hydrolyzation; a step of generating fragments from the separated amino acid; and a step of selecting and analyzing a predetermined fragment that contains an ? carbon and does not contain a side chain from the generated fragments, by mass spectrometry.
    Type: Grant
    Filed: May 10, 2016
    Date of Patent: August 25, 2020
    Assignee: KAGAMI INC.
