In studies of acid, alkaline, and enzyme hydrolysis of these compounds, it was established that CH 3-groups in position 3 of uracil do not exert a significant influence on reactivity of the phosphoamide bond in uridylyl-(5′ → … WebPhosphoramidates are the aliphatic amides of phosphoric acid and are widely employed in the synthesis of differentially protected phosphate esters as more stable alternatives to …
WebBased on the type of chemical bond formed with the phosphate group, amino acids can be divided into several groups. The first type of bond is a simple phosphoamide bond, when the phosphate group is attached to the hydroxyl residue of an amino acid (Ser, Thr, and Tyr); this type of bond is extremely stable chemically, and is resistant to both acids Webformation of a phosphoamide bond. This is similar to a reaction found in naturally occurring proteins such as guanyltransferase, and DNA and RNA ligases that form phosphoamide bonds as enzyme-nucleotidyl intermediates during cap formation and ligation events (7–9).
