This model, however, is only valid for chain molecules at zero Kelvin. When 7V 0 the chain parts possess thermal energy vibration causes them to move in random directions, which always results in a contraction of the stretched chain. The chain tends to a state of higher probability, and eventually reaches a fully unoriented random conformation, as described in 2.4 ( random walk conformation ). To... 

It was observed that in both the low- and high-temperature transitions, a higher transition temperature is conducive to both more accentuated lattice contractions and larger change in the intensities of the superlattice reflections. It therefore is considered that the mechanism of the high-temperature transition must be similar to that of the low-temperature transitions. To recapitulate, oxygen in the normal lattice sites enter the interstitial sites driven by the thermal energy available at the transition temperature, and this redistribution intensifies the superlattice reflections and simultaneously causes the lattice contractions. 

Contraction of elastic matrices occurs as the temperature is raised through the temperature interval of Figure 5.5A this constitutes the input of thermal energy (TE), measurable as the heat of the transition seen in Figure 5.1C. Visible contraction also occurs as any of the independent variables move through the transition zone in Figure 5.5B. Depending on the composition of the model protein that consti-...
