Alcohol dehydrogenase is widely used in biochemical research and industrial applications. In laboratories, it plays a crucial role in enzymatic assays to measure ethanol concentrations in biological samples. It is also employed in the production of biofuels, where it facilitates the conversion of alcohols into aldehydes or ketones, aiding in the development of renewable energy sources. Additionally, it is utilized in the pharmaceutical industry for the synthesis of chiral compounds, which are essential in manufacturing drugs with specific stereochemical properties. In environmental monitoring, alcohol dehydrogenase helps detect and quantify ethanol in water and air samples, ensuring compliance with safety standards. Its recombinant form ensures higher purity and efficiency, making it a preferred choice for these applications.
