In chemistry, a phosphodiester bond occurs when exactly two of the hydroxyl groups (−OH) in phosphoric acid react with hydroxyl groups on other molecules to form two ester bonds. The "bond" involves this linkage C−O−PO − 2 O−C. [1]

Jun 16, 2022 · A phosphodiester bond is a chemical bond that forms when exactly two hydroxyl groups in phosphoric acid react with a hydroxyl group on other molecules forming ester bonds. It is found in the DNA and RNA backbone.

In DNA and RNA, the phosphodiester bond is the linkage between the 3' carbon atom of one sugar molecule and the 5' carbon atom of another, deoxyribose in DNA and ribose in RNA. Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds.

Jun 2, 2024 · A phosphodiester bond is formed between two sugar molecules and a phosphate group. This bond connects nucleotides, which form the backbone of a DNA or RNA chain.

Feb 20, 2024 · In DNA or RNA, phosphodiester bonds are the bonds between the phosphate group and the sugar molecules. DNA contains nitrogenous bases (adenine, guanine, cytosine, thymine, or an uracil if it’s RNA), a sugar molecule (deoxyribose if DNA or ribose if RNA), and a triphosphate group (Figure 1).

The phosphodiester bond is a covalent linkage between the phosphate of one nucleotide and the hydroxyl (OH) group attached to the 3′ carbon of the deoxyribose sugar in an adjacent nucleotide, forming what is known as the “sugar-phosphate backbone” of DNA.

Phosphodiester bonds serve as the structural foundation for all life forms. A phosphodiester bond is formed by reacting two hydroxyl groups in phosphoric acid with the hydroxyl group on other molecules to produce an ester link.

Jan 29, 2025 · The meaning of PHOSPHODIESTER BOND is a covalent bond in RNA or DNA that holds a polynucleotide chain together by joining a phosphate group at position 5 in the pentose sugar of one nucleotide to the hydroxyl group at position 3 in the pentose sugar of the next nucleotide —called also phosphodiester linkage.

A phosphodiester bond is a covalent chemical bond that links the phosphate group of one nucleotide to the sugar (deoxyribose) of the next nucleotide, forming the backbone of DNA molecules. This bond is crucial for the structural integrity and information storage capabilities of …

Bonds between phosphate group and pentose sugar in nucleic acids. In nucleic acids, such as DNA and RNA, the phosphate group is connected to the pentose sugar (either deoxyribose in DNA or ribose in RNA) through a covalent bond. This bond is known as a phosphodiester bond.
