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." WebA similar work was carried out with sucrose solutions and kinematic viscosity data were reported from 20 to 50°C and molalities in the range of 0.5 to 4.5 moles/kg (14.61 to …
