D-(-)-Mannose is widely used in the medical and health industry due to its ability to support urinary tract health. It is commonly taken as a dietary supplement to help prevent or manage urinary tract infections (UTIs) by preventing harmful bacteria, such as E. coli, from adhering to the walls of the urinary tract. This allows the bacteria to be flushed out of the body naturally. Additionally, it is used in the food industry as a low-calorie sweetener and stabilizer in various products. In biotechnology, it serves as a key component in the production of glycoproteins and other biomolecules. Its role in research includes studying cell signaling and carbohydrate metabolism.
