Glucose dehydrogenase is widely used in biosensors for blood glucose monitoring, particularly in diabetic patients. It plays a crucial role in converting glucose into gluconolactone, enabling the detection of glucose levels in blood samples. This enzyme is preferred due to its stability and specificity, making it a reliable component in diagnostic devices. Additionally, it is utilized in the food industry to measure glucose content in products, ensuring quality control. In biotechnology, glucose dehydrogenase is employed in enzymatic assays and research applications to study glucose metabolism and related biochemical pathways. Its ability to function without oxygen makes it suitable for use in anaerobic environments, expanding its utility in various scientific and industrial processes.
