Steady‐state conductivity and dielectric measurements in the range of 10 −5 Hz to 33 GHz are reported for bovine serum albumin and lysozyme as a function of hydration and NaCl content. The electrical properties are understandable in terms of the existence of charge carriers whose hopping‐type transport process is directly influenced by the nature of the protein‐water interaction. These mobile charges are considered to be protons originating from ionizable carboxylic groups.
