Thermostable enzymes are proteins that remain active and functional at high temperatures. These enzymes are often derived from organisms that thrive in extreme environments, such as thermophiles, which are heat-loving microorganisms. Their stability at elevated temperatures makes them valuable in various industrial applications, including biotechnology and food processing. Due to their ability to withstand heat, thermostable enzymes can speed up chemical reactions without denaturing, or losing their structure. This property allows for more efficient processes, such as in the production of biofuels and the breakdown of complex molecules. Their use can lead to cost savings and improved sustainability in various industries.
