Outline of Final Research Achievements

Homocysteine (Hcy), a sulfur-containing amino acid, is a representative intermediate metabolite of methionine (Met) to cysteine (Cys) via several intermediates. An elevated level of Hcy in plasma plays an important role in diseases such as neural tube defects and Down syndrome. In this study, development of Hcy and its related compounds in hair was examined. As a result, HPLC-fluorescence detection coupled with tris(2-carboxylethyl)phosphine could determine Met and Cys in human hair. And it's clalified that the Hcy concentration in hair was less than that in plasma.

Academic Significance and Societal Importance of the Research Achievements

ヒト毛髪中のメチオニンおよびシステインのHPLC-蛍光検出定量法を確立した。本法により毛髪の前処理条件を詳細に検討することによりメラニン結合性のメチオニンおよびシステインの定量が可能であった。またヒト毛髪に含まれるホモシステイン濃度が血漿などに比べて非常に低濃度であるとこが明らかとなった。今後はこれらの化合物濃度と血漿中ホモシステイン濃度との相関性を明らかにすることで,診断マーカーとしての有用性を評価していく。
