Phosphate ester definition
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 halophosphates.88 They have been used as prodrug moieties to enhance water solubility 89 and to enhance the therapeutic potential of a parent drug. 90 In addition, they … WebFeb 13, 2024 · Phosphate and its derivative functional groups are ubiquitous in biomolecules. Phosphate linked to a single organic group is called a phosphate ester; when it has two links to organic groups it is called a phosphate diester. A linkage between two phosphates creates a phosphate anhydride. Organic phosphates

In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, aka. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO 4] is derived from phosphoric acid by the removal of three protons H . Removal of one or two protons gives the dihydr… WebPhosphatases or phosphomonoesterases are the hydrolytic enzymes that cleave the ester bond between the phosphate group and the organic residue of the organic phosphates. Based on the optimum pH for the activity, phosphatases are of two kinds: acid and alkaline.
