Where is the phosphate group in DNA? The phosphate group present in the nucleotide creates a covalent bond with the sugar molecule of the adjacent nucleotide to form a long chain of the nucleotide monomers. The sugar-phosphate groups form a backbone in the single strand of DNA. The phosphate...
For the formation of DNA strand, huge amount of energy is required. We know that ATP (adenosine triphosphate) is the main energy molecule for... Learn more about this topic: DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds ...
Both phosphate groups of lipid A at C-1 and C-4′ may carry (polar) substituents, although examples in which the phosphate groups are free are known. The substitution of phosphate groups is often nonstoichiometric, as exemplified with N. meningitidis lipid A (Fig. 6). In this interesting ...

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule. DNA and RNA are composed of nucleotides that are linked to one another in a chain...
Novel P(III) bisamidite reagents as phosphorus protecting groups, nucleoside phosphoramidite intermediates, and synthetic processes for making the same are disclosed. Furthermore, oligomeric compounds are prepared through the protection of one or more internucleosidic phosphorus functionalities, preferably fo...
Ribose-5-phosphate (R5P) is a necessary precursor for thebiosynthesisofnucleosides, which in turn are converted to nucleotides by the addition of phosphate groups. In parallel, NADPH are reducing molecules involved inreactive oxygen species(ROS) metabolism, anabolism, andoxidative phosphorylation, and...
1). Rapidly dividing cells have high needs for pentose phosphates; this demand is particularly high for cancer cells, in which the PPP provides about 85% of pentoses incorporated into DNA [10]. Thus, the first condition that strongly affects PPP activity is the rate of cell proliferation: ...
