D-Ribose 5-phosphate disodium salt (CAS 18265-46-8)

D-Ribose 5-phosphate disodium salt is an organic salt composed of D-ribose, a pentose sugar, and phosphate groups, with two sodium ions bound to enhance its solubility and stability. Scientifically, D-Ribose 5-phosphate disodium salt finds wide application in biochemical and metabolic studies. It serves as an essential intermediate in the pentose phosphate pathway (PPP), a fundamental metabolic pathway that generates ribose-5-phosphate and NADPH. Ribose-5-phosphate is vital for the synthesis of nucleotides, coenzymes, and nucleic acids, making it an essential precursor in cellular processes such as DNA and RNA synthesis. In addition to its role in nucleotide synthesis, D-Ribose 5-phosphate disodium salt is involved in various other biochemical pathways. It participates in the biosynthesis of amino acids, such as histidine and tryptophan, and contributes to the formation of important biomolecules like ATP (adenosine triphosphate) and NADH (nicotinamide adenine dinucleotide). Its presence is for the proper functioning and energy metabolism of cells. The mechanism of action of D-Ribose 5-phosphate disodium salt lies in its ability to serve as a phosphorylated sugar molecule in various enzymatic reactions. It acts as a substrate for enzymes involved in nucleotide synthesis, allowing for the incorporation of ribose-5-phosphate into the growing nucleotide chain. Additionally, it acts as a donor of phosphoryl groups, facilitating the transfer of phosphate groups to other molecules and participating in the regulation of metabolic processes.
