WebApr 28, 2024 · Phosphate, chemical formula PO 43-, is a chemical compound made up of one phosphorus and four oxygen atoms. When it is attached to a molecule containing carbon, it is called a phosphate group. … WebThe 3' carbon of one sugar is bonded to the 5' phosphate of the adjacent sugar. Specifically, the phosphodiester bond links the 3' carbon atom of one sugar molecule and the 5' carbon atom of another (hence the name, 3', 5' phosphodiester linkage). These saccharide groups are derived from deoxyribose in DNA and ribose in RNA.
