四十年代已经发现蛋白质内存在着高效率的能量转移过程。如肌红蛋白(Mb)的血红素部分结合了一氧化碳形成复合体Mb-Co后,用对应于该复合体最大吸收位置的546nm的光照射射,吸收的光毫无损失地切断肌红蛋白的Fe-Co键,使Co游离; Forty forties have been found in the protein memory efficient energy transfer process. If the heme portion of myoglobin (Mb) binds to carbon monoxide to form the complex Mb-Co, it is irradiated with light of 546 nm corresponding to the maximum absorption position of the complex, and the absorbed light is cut off without any loss of myoglobin Fe-Co bond to make Co free;
