overview | L-gulose is a rare hexalose, which can be used as a synthetic precursor of vitamin C and a drug intermediate for the synthesis of nucleoside anti-HIV drugs. It has high economic value. At present, chemical synthesis and enzymatic synthesis are the two main preparation methods of rare sugars, but the chemical synthesis method of rare sugars is complicated, with low yield and serious environmental pollution. What is important is that the rare sugars synthesized are scarce and cannot meet the market demand. |
Product use | Gulose is a kind of hexalose, which is the epimomer of galactose at the C 3 position. Galactose can produce gulose by epimerase treatment. Gulose is a good low-energy food sweetener and filler, which can effectively promote the growth and reproduction of the beneficial bacteria Bifidobacterium in the human body, and has a variety of physiological effects such as inhibiting hyperglycemia, improving intestinal flora, and preventing dental caries. Gulose also has obvious anti-tumor effect and is expected to be developed into anti-tumor functional food. |
biological activity | L-Gulose is an unnatural monosaccharide. It is an intermediate of L-Ascorbate (vitamin C) biosynthesis. |
