  • A differential pair of planar thin-film interdigitated electrodes, deposited on a ceramic pad, was used as a conductometric transducer. The three-enzyme system (invertase, mutarotase, glucose oxidase), immobilized on the transducer surface, was used as a bioselective element. The ratio between enzym

  • システインが酸化されて2分子結合したもの。
  • 溶解度は低い。
  • システインのpK1=1.92, pK=10.7がそのまま適応できるとすれば、等電点であるpI=6.31に向かって溶解度が低下する。このため、酸性条件でシスチン結石が形成されやすいと考えられる。
