Simulate experiment , which rice wine was aerated and added with h2o2 , and the content analyses showed that the oxygen dissolved in rice wine reacting with amyloses , proteins and tannin may produce the visible turbidness ( oxidizing sedimentation ) 通過向酒體中通入空氣和添加過氧化氫等模擬實驗和成分分析表明,酒體中的溶解氧可與多糖、蛋白質(zhì)和單寧等作用形成渾濁(即氧化沉淀) 。
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(zhì)中, hemin催化溶解氧氧化溴鄰苯三酚紅的褪色反應(yīng)。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(shù)催化常數(shù)和專一性常數(shù)分別為3 . 710
