D-Turanose is primarily used in biochemical research as a substrate to study enzyme activity, particularly in the context of carbohydrate metabolism. It serves as a valuable tool for investigating the specificity and function of enzymes like glycosidases and glycosyltransferases. Additionally, it is utilized in the study of sugar transport mechanisms in cells, helping to elucidate pathways involved in energy production and storage. In food science, D-Turanose can be employed to explore its potential as a low-glycemic sweetener, offering insights into its digestibility and metabolic effects. Its role in glycobiology also extends to the development of novel glycoconjugates for therapeutic applications.
