Ribose is a carbohydrate with the formula C5H10O5; specifically, it is a pentose monosaccharide (simple sugar) with linear form H−(C=O)−(CHOH)4−H, which has all the hydroxyl groups on the same side in the Fischer projection.The term may refer to either of two enantiomers. The term usually indicates D-ribose, which occurs widely in nature and is discussed here. Its synthetic mirror image, L-ribose, is not found in nature. It is produced by microorganism fermentation of glucose in a fermentation culture medium without adding calcium carbonate.

L-Ribose is a very important saccharide concered with life and heredity, which plays a very important role in physiology. D-Ribose exist abundantly in the nature, however, the enantiomers L-Ribose does not exist in the nature, which is a rare and expensive saccharide. L-Ribose has effective anticancer ability and little side-effect on normal cell. L-Ribose is an important medicament intermediate. Because the application area of L-Ribose is expanding quickly, the requirement of L-Ribose in the globe is increasing year after year. New ways of preparing L-Ribose are discovered. Our company provides highly purity L-Ribose, which can be widely used in pharmaceuticals and biochemical.
