Ribose is a naturally-occurring carbohydrate with the formula C 5 H 10 O 5 ; 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 5-carbon monosaccharide ribose is an important component of coenzymes (e.g. ATP, FAD and NAD) and the backbone of the genetic molecule known as RNA.

Deoxyribose

2-deoxyribose-deoxyriboseDeoxyribofuranose
It is related to deoxyribose, which is found in DNA.
Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom.

Ribose is a naturally-occurring carbohydrate with the formula C 5 H 10 O 5 ; 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. In November 2019, scientists reported detecting, for the first time, sugar molecules, including ribose, in meteorites, suggesting that chemical processes on asteroids can produce some fundamentally essential bio-ingredients important to life, and supporting the notion of an RNA world prior to a DNA-based origin of life on Earth, and possibly, as well, the notion of panspermia.
DNA and RNA are built up of the monosaccharides deoxyribose and ribose, respectively.

RNA

The ribose β--ribofuranose forms part of the backbone of RNA.
Each nucleotide in RNA contains a ribose sugar, with carbons numbered 1' through 5'.

Adenosine triphosphate

ATPadenosine triphosphate (ATP)adenosine 5'-triphosphate
Phosphorylated derivatives of ribose such as ATP and NADH play central roles in metabolism.
From the perspective of biochemistry, ATP is classified as a nucleoside triphosphate, which indicates that it consists of three components: a nitrogenous base (adenine), the sugar ribose, and the triphosphate.

DNA

deoxyribonucleic aciddouble-stranded DNAdsDNA
It is related to deoxyribose, which is found in DNA.
One major difference between DNA and RNA is the sugar, with the 2-deoxyribose in DNA being replaced by the alternative pentose sugar ribose in RNA.

Nicotinamide adenine dinucleotide

NAD + NADHNAD
Phosphorylated derivatives of ribose such as ATP and NADH play central roles in metabolism.
The nucleosides each contain a ribose ring, one with adenine attached to the first carbon atom (the 1' position) and the other with nicotinamide at this position.

Metabolism
