WebJun 26, 1992 · The theory and experiment suggest that the dominant factor in markedly reducing the rate of conformational changes in myoglobin at low temperatures (<200 K) is the very high viscosity (>10 7 centipoise) of the glycerol-water solvent. That is, at low temperatures conformational substates may not be "frozen" so much as "stuck." WebNov 22, 2024 · 2.2.
