Steady-state conductivity measurements and dielectric measurements in the frequency range 10(-5) to 100 Hz are reported for samples of bovine serum albumin, casein, and lysozyme complexed with methylglyoxal. Compared with the untreated proteins, the brown complexed proteins exhibit an increased conductivity and free electron spin density, together with a low-frequency dielectric dispersion. These results can be taken as evidence that the interaction with methylglyoxal results in the proteins possessing an increased electronic activity associated with the creation of mobile electron holes within the valence band states of the protein molecules.
报告了牛血清白蛋白、酪蛋白和溶菌酶与甲基乙二醛复合样品在10^(-5)至100Hz频率范围内的稳态电导率测量和介电测量结果。与未处理的蛋白质相比，棕色复合蛋白质表现出电导率和自由电子自旋密度增加，以及低频介电色散。这些结果可作为证据，表明与甲基乙二醛的相互作用导致蛋白质具有增加的电子活性，这与蛋白质分子价带态中移动电子空穴的产生有关。
