WebPhosphate ester : An ester derived from an alcohol and phosphoric acid. Also called organo phosphate compounds because these molecules have a phosphate group bonded to carbon. In DNA and RNA , a phosphodiester group (in the black circle) joins the 3'-carbon on the ribofuranose of one nucleobase to the 5'-carbon on the next nucleobase. WebPhosphate esters and anhydrides dominate the living world but are seldom used as intermediates by organic chemists. Phosphoric acid is specially adapted for its role in nucleic acids because it can link two nucleotides and still ionize; the resulting negative charge serves both to stabilize the diesters against hydrolysis and to retain the molecules …
