a pentose sugar important as a component of ribonucleic acid
A naturally occurring pentose sugar, which is a component of the nucleosides and nucleotides that comprise the nucleic acid biopolymer, RNA. It is also found in riboflavin.
Ribose is an organic compound with the formula C5H10O5; specifically, a monosaccharide with linear form H−−(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 and is of limited interest. D-Ribose was first reported in 1891 by Emil Fischer. It is a C'-2 carbon epimer of the sugar D-arabinose and ribose itself is named as a transposition of the name of arabinose. Ribose forms part of the backbone of RNA. It is related to deoxyribose, which is found in DNA. Phosphorylated derivatives of ribose such as ATP and NADH play central roles in metabolism. cAMP and cGMP, formed from ATP and GTP, serve as secondary messengers in some signalling pathways.
