A phosphate monoester group, a phosphorus anhydride linkage, two amide groups and the acetyl group has to be identified from the given structure of acetyl coenzyme A. Concept Introduction: Phosphoric Acid: It is an inorganic acid having similarities with a carboxylic acid . There are three different acidic hydrogens which causes it to form three anions. Phosphate Ester: Phosphate esters are prepared by the reaction of a phosphoric acid and an alcohol molecule with the elimination of water molecule. Alcohol can react with one − O H group forming Phosphate monoester . Alcohol can react with two − O H groups of phosphoric acid forming Phosphate diester. Alcohol can react with three − O H groups of phosphoric acid forming Phosphate triester. Amide: One − N H 2 , − N H R ' or − N R ' 2 group is attached to the carbonyl carbon atom of the compound. It is represented as R C O N R ' 2 . Phosphoric Acid Anhydride: It is formed when two phosphoric acid molecules react with the elimination of water molecule. It has atleast one P − O − P anhydride linkage. Esters containing one P − O − P anhydride bond are known as diphosphates whereas two P − O − P anhydride bond are known as triphosphates.

What is the chemical importance of the negative charge on the phosphate group? Be asspecific as possible. In what ways might this negative charge have beenthermodynamically useful during the evolution of ATP-binding proteins?

One prominent theory on life origins was that RNA enzymes came into existence early inthe prebiotic history of Earth and were able to do basic chemical catalyses. Eventually,this “RNA-world” was overtaken by the stability of DNA as an information carrier and thediversity of catalytic functions capable of being performed by polypeptides. Is the RNA world hypothesis is a well-founded model?
