Thermostability refers to the ability of a substance or system to remain stable and functional at elevated temperatures. This property is crucial in various fields, including materials science, biology, and chemistry. In materials science, thermostable materials are essential for applications requiring resistance to heat, such as in aerospace components, engine parts, and high-temperature industrial processes. Polymers, ceramics, and certain metals often exhibit good thermostability.

In biological contexts, thermostability is particularly relevant to enzymes and proteins. Thermostable enzymes, often found in extremophilic microorganisms, can function at temperatures that would denature most other proteins. This characteristic makes them valuable tools in biotechnology, including industrial biocatalysis, PCR amplification in molecular biology, and detergent formulations. The ability of a protein to withstand heat is often linked to its specific amino acid sequence, its three-dimensional structure, and the presence of stabilizing interactions like disulfide bonds or salt bridges.

Chemically, thermostability can describe the resistance of chemical compounds to decomposition or unwanted reactions when heated. This is important for the storage, handling, and processing of many chemicals. Understanding and enhancing thermostability is a continuous area of research, aiming to develop materials and biological systems that can perform reliably under demanding thermal conditions.
