Beta-D-ribose is a colorless, odorless crystalline compound, highly soluble in water but less soluble in alcohol. It is an aldopentose.
Production and presence
The molecule occurs in all living organisms as the carbohydrate component of RNA. The sugar-phosphate backbone of the RNA consists of ribose and phosphate molecules. Nitrogen-containing organic bases, which encode the amino acid sequence of proteins are attached to the ribose molecules. It is also found in nucleotide coenzymes such as NAD, NADP and ATP.
ATP is the main source of energy for cells.
An acyl-carrier coenzyme taking part in both anabolic and catabolic processes.
A polynucleotid made up of phosphoric acid, ribose, and nucleobases (cytosine, uracil, adenine and guanine).
A component of DNA, it contains one less hydroxyl group than β-D-ribose.
The open-chain version of ribose, which occurs naturally in nucleic acids, coenzymes, nucleotides and nucleosides.
A compound ion formed when a phosphoric acid molecule releases a proton.
NAD⁺ is a coenzyme that plays an important role mainly in catabolic processes, while NADP is important in anabolic processes as hydrogen carriers.
A heterocyclic aromatic organic compound, its derivatives include guanine and adenine.
A heterocyclic organic compound, its derivatives are thymine, cytosine and uracil.
