Abstract
Dielectric and conductivity measurements are reported for bovine serum albumin as a function of hydration. Strong evidence is found for the existence of mobile charges whose short- and long-range hopping motion strongly depends on the physical state of the protein-bound water. These charges are considered to be protons. Insights into the nature of the electrical properties of protein-methylglyoxal complexes are provided, and the possibilities for correlated proton-electron motions are outlined.
摘要
报道了牛血清白蛋白介电常数和电导率随水合作用的测量结果。发现了有力证据，证明存在移动电荷，其短程和长程跳跃运动强烈依赖于与蛋白质结合的水的物理状态。这些电荷被认为是质子。对蛋白质-甲基乙二醛复合物电学性质的本质提供了见解，并概述了质子-电子相关运动的可能性。
