WebFeb 20, 2024 · Phosphodiester Bond is involved in the polymerization of nucleotides. When polymerization occurs, the -OH group gets attached to 3 carbon of nucleotides (sugar molecules) with the phosphate group’s -OH of another nucleotide. Hydrogen and hydroxyl may combine with each other. 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−2O−C. Discussion of phosphodiesters is dominated by their prevalence in DNA and RNA, but phosphodiesters occur in other biomolecules, e.g. acyl carrier proteins.
