Strong covalent bonds form between the phosphate group and two 5-carbon ring carbohydrates (pentoses) over two ester bonds. Just replace phosphate with a carboxylic acid and it should make more sense. All simple nucleotides have this phosphoester bond. Can someone please explain what a phosphodiester bond is. Phosphoesters form the backbone of DNA molecules. Join now. Phosphodiester bonds are central to all life on Earth,[fn 1] as they make up the backbone of the strands of nucleic acid. See Below Nucleotide Monophosphates, NMPs, are nucleosides that have 1 phosphate group. If nothing, then you have seen it in movies like Spiderman: a winding, ladder-like structure, like a spiral staircase.
