Phosphoester Bonds
Phosphoester bonds are covalent bonds between a phosphorous and a carbon atom. It is a basic bond in biomolecular structures like nucleic acids including our genetic material DNA.[2]
Chemistry[edit]
Phosphoester Bond is formed when a phosphate (PO4)3- moiety reacts with the hydroxyl group (OH−) linked to a carbon atom of an aromatic or Aliphatic hydrocarbon, removing H2O.
Generally -P=(O)-O-C- (-phosphorus(double bonded Oxygen in side chain)-oxygen-carbon-).
Biology[edit]
Phosphoester Bonds in Biomolecules are formed when a phosphate (PO4)3- moiety reacts with the hydroxyl group (OH−) linked to the 3' (pronounced as 3 prime) carbon atom of a sugar of Nucleoside forming a Nucleotide.Generally -P=(O)-O-C- (-phosphorus(double bonded Oxygen in side chain)-oxygen-carbon-).
More[edit]
A phosphoester bond is analogous to an Ester bond i.e. R-C=(O)-O-R' replacing the Carbon (C) atom ,which is bonded to two Oxygen (O) atoms, (one by a double bond and another by a single bond) with a Phosphorus (P) atom.
When two phosphoester bonds are present on each side of the Phosphorus (P) atom (-C-O-P=(O)-O-C-) it is called Phosphodiester Bonds.
