化学计算的反应: ROOH+2Fe~(++)+2H~(+)→ROH+2Fe~(+++)+H_2O (D) 过氧化物的诱导还原: ROOH+S→ROH+S-O (E) 亚铁离子的诱导(空气)氧化: O_2+4Fe~(++)+4H~(+)→4Fe~(+++)+2H_2O (F) 此处,S是“被酶作用物”,S—O是其氧化产物。在这些方程式中,过氧化物用有机的“含氢过氧化物”ROOH表示,因为这一类型的过氧化物,在工业上最严重要。被酶作用物的氧化过程(在反应E中具有接受物的功用),系于它的本性;被酶作用物可能是原物料(如汽油,猪脂等),其中过氧化物的含量正要测定的,或者是指溶剂,或者就是含氢过氧化物的分子自己。由反应D和反应E所构成的诱导反应中,过氧化物是作用物,亚铁离子是诱导剂;但在反应D和反应F所构成的诱导反应中,亚铁离子是作用物,过氧化物是诱导剂,而氧分子是接受物。每个总的诱导反应,E和F,祗含作用物和接受物,这是诱导链
Stoichiometric reaction: ROOH + 2Fe ~ (++) + 2H ~ (+) → ROH + 2Fe ~ (+++) + H_2O (D) Induced reduction of peroxide: ROOH + S → ROH + SO ) Ferrous ion induced (air) oxidation: O 2 + 4 Fe ++ ++ + 4+ ++ 4+ ++ 2H 2 O (F) Here, S is an “enzyme substrate” S-O is its oxidation product. In these equations, peroxide is represented by the organic “hydroperoxide” ROOH, as this type of peroxide is the most industrially important. Oxidation by the enzyme substrate (in the reaction E has the function of receptor), in its nature; enzyme substrate may be the original material (such as gasoline, lard, etc.), in which the content of peroxide is Measured, or refers to the solvent, or hydrogen peroxide is the molecule itself. In the reaction induced by reaction D and reaction E, peroxide is the active substance and ferrous ion is the inducer. However, in the reaction induced by reaction D and reaction F, the ferrous ions are the reactants and the peroxide The material is an inducer, and the oxygen molecule is an acceptor. Each total induction reaction, E and F, contains only actors and receptors, which are induced chains
