l-tartaric acid monomethyl ester 3

Esters of Phosphoric Acid

Just as carboxylic acids do inorganic acids such as nitric acid (HNO 3) sulfuric acid (H 2 SO 4) and phosphoric acid (H 3 PO 4) also form esters The esters of phosphoric acid are especially important in biochemistry A phosphoric acid molecule can form a monoalkyl a dialkyl or a trialkyl ester by reaction with one two or three molecules of an alcohol Esters of pyrophosphoric acid
