D-Ribose occurs widely in nature. It forms the 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 healthcare-related products or even food additive
