Allium属植物成分とVitamin B₁との反応に関する研究 (III) Allithiamineに対するL-Cysteineの作用

抄録

Application of equimolar amount of L-cysteine to allithiamine (V) results in its facile reduction to thiamine, and the allylmercapto group thereby liberated combines with L-cysteine to form S-allylmercapto-L-cysteine (VII). The mechanism of biological change of allithiamine (V) to thiamine is assumed to follow such a reaction by the SH-containing compounds, such as cysteine or glutathione, or by proteins present in the body.
