醌在自然界中广为存在,且在生物体内的生化过程中起重要作用。某些醌的衍生物被用作药物或作为酶反应和光合成中的电子传递体。为了解它们的生理和生化功能,人们已利用电化学技术研究了很多生物意义的醌/氢醌体系的氧化还原反应。虽然新近已提出所述反应是按包含电子交换和质子交换的一系列步骤进行的,涉及到示于相应九元方格图式中的9个可能的物种,但是由于反应中间物的检测与表征尚为短缺,因而对某一给定体系的反应机
Quinones are widespread in nature and play an important role in the biochemical processes in living organisms. Certain quinone derivatives are used as drugs or as electron mediators in enzymatic reactions and photosynthesis. In order to understand their physiological and biochemical functions, electrochemical biochemical techniques have been used to study the redox reactions of many biologically meaningful quinone / hydroquinone systems. Although it has recently been proposed that the reaction be carried out in a series of steps involving both electronic exchange and proton exchange, involving the nine possible species shown in the corresponding nine-quaternary scheme, due to the detection and characterization of the reaction intermediates It is still a shortage, and therefore a reaction to a given system
