7DG is primarily utilized in biochemical research as a tool to study glucose metabolism and its related pathways. It serves as an analog of glucose, allowing scientists to investigate cellular uptake mechanisms and metabolic processes without the interference of normal glucose metabolism. This compound is particularly valuable in cancer research, where it helps to understand how cancer cells alter their glucose consumption to support rapid growth and proliferation. Additionally, 7DG is used in imaging studies to track glucose uptake in tissues, providing insights into metabolic disorders such as diabetes. Its application extends to drug development, where it aids in screening compounds that target glucose transporters or metabolic enzymes.
