Applications

D-ribose, as a pharmaceutical intermediate, has been widely used in the synthesis of riboflavin (VB2), pyran ribose and anti-virus, anti-tumor nucleoside. In health care, D-ribose has been used to treat myocardial ischemia, diabetes and muscle pain (caused by exercise); in food industry, D-ribose, as a natural food sweetener, has been widespread used in Japan and other developed countries.
