D-Ribose occurs widely in nature. It forms backbone of RNA, a biopolymer that is the basis of genetic transcription. It is related to deoxyribose, as found in DNA. Once phosphorylated, ribose can become a subunit of ATP, NADH, and several other compounds that are critical to metabolism. D-Ribose is the material used in the synthesis of Vitamin B2(Riboflavin}, Tetra-O• AcetyI--Ribose and nucleoside etc. D-Ribose is also used in the production of health care-related products or even food additive.
