Phosphodiester bond - The School of Biomedical …
WebPhosphodiester bond forms when a phosphoric acid molecule (H 3 PO 4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function. Webphosphodiester bond (fŏs′fō-dī-ĕs′tər) n. A covalent chemical bond that links two carbon atoms through a phosphate group, especially the bonds that link the pentose sugars of adjacent nucleotides in polynucleotide chains of RNA and DNA.
