Ｆｅｎｔｏｎ反应产生的·ＯＨ进攻脱氧核糖，生成的丙二醛与硫代巴比妥酸在低ｐＨ条件下加热生成红色加合物。用分光光度法研究抗坏血酸对Ｆｅｎｔｏｎ反应生成·ＯＨ的影响。结果表明，在适当条件下，抗坏血酸能显著促进·ＯＨ的生成；抗坏血酸亦是一种有效的·ＯＨ清除剂。·ＯＨ清除剂与脱氧核糖竟争·ＯＨ，根据对显色反应的抑制及脉冲射解试验测得·ＯＨ与脱氧核糖反应的速率常数，推出·ＯＨ与清除剂反应的速率常数。
The · OH attack by Fenton reaction attacks deoxyribose and the resulting malondialdehyde and thiobarbituric acid are heated at low pH to produce a red adduct. Study on the Effect of Ascorbic Acid on the Formation of · OH by Fenton Reaction by Spectrophotometry. The results showed that ascorbic acid could significantly promote the formation of · OH under appropriate conditions; ascorbic acid was also a effective · OH scavenger. · OH scavenger and deoxyribose competitive · OH, according to the inhibition of color reaction and pulsed radiolysis test · OH and deoxyribose reaction rate constant, the introduction of · OH and scavenger reaction rate constant.
