hemin n.【生物化學】氯高鐵血紅素。

Mol l , artemisinin can be reduced via the hemin - catalysis and its original cathodic peak at - 1 . 08v completely disappeared . the cathodic overpotential of artemisinin is decreased ca . 600mv . this process is verified by the fact that complex edta - fe can also promote the artemisinin reduction with decreasing the cathodic overpotential of artemisinin for 590mv . these results show that the reduction of artemisinin at the glassy carbon electrode is a catalytic process with the aids of hemin . hemin can greatly decrease the cathodic activation energy of the reduction of artemisinin and promote the decomposition of artemisinin Mol l氯化血紅素存在下,青蒿素仍可被催化還原,陰極過電位降低了600mv 。配合物edta - fe具有類似氯化血紅素的催化性質,它降低了qhs陰極過電位590mv 。在這個體系中,青蒿素在碳電極上的還原是一個借助于氯化血紅素催化的還原過程,氯化血紅素的存在降低了青蒿素還原活化能,促進了青蒿素的分解。

A novel catalytic property of hemin is described . in ammonium buffer medium of ph 8 . 08 . 9 , hemin has an ability to catalyze the decoloration of bromopyro - gallol red . oxygen dissolved in solution plays a role as an oxidant in the reaction . with sodium dodecylbenzenesulfonate and ethanol as effect - enhancing agents , the catalytic system obeys the michaelis - menten equation of enzymatic catalysis . the michaelis constant , catalytic constant and specificity constant of the system are estimated by lineweaver - burk plot to be 3 . 710 在ph 8 . 08 . 9氨性緩沖介質中, hemin催化溶解氧氧化溴鄰苯三酚紅的褪色反應。在sdbs和30 %乙醇的增效作用下,催化體系服從michaelis - menten方程。用lineweaver - burk作圖法求得米氏常數催化常數和專一性常數分別為3 . 710

The interaction between artemisinin and hemin was investigated by electrochemical methods . artemisinin was irreversibly reduced at - 1 . 08v via a two - electron transfer at the glassy carbon electrode . in the presence of concentration of hemin as low as 4 . 010 青蒿素在玻璃碳電極上于- 1 . 08v處能發生一個2電子轉移的不可逆還原。即使在低至4 . 010

Respectively . the mechanism of the hemin oxidase - like catalytic system is discussed . based on this , hemin can be spectrophotometrically determined by equilibrium and kinetic procedures with a linear range and 3 利用該催化體系,用反應平衡法和動力學法均可分光光度定量hemin ,線性范圍為2 . 010

“ through surveillance ( 3 ) we found out that xiang xiang had gradually adapted to the wild environment , “ zhang hemin , director of the centre , said in july 中心主任去年七月說: “通過跟蹤觀察,我們發現祥祥已經逐漸適應了野外環境。 ”
