WebMar 1, 2000 · The stability of the constituent α-helices also appears to contribute to protein thermal stability. Thermophilic proteins have a higher proportion of residues in helical conformation. Helix-favoring residue Arg occurs more frequently in α-helices of thermophilic proteins, whereas helix-disfavoring residues Cys, His and Pro have lower ... WebThe materials having low thermal conductivity and high thermal expansion coefficient are vulnerable to thermal shock. Thermal shock can be prevented by reducing the thermal gradient through changing the temperature more slowly, or by improving the robustness of a material against thermal shock through increasing a ‘thermal shock parameter’.
