The reaction in which phosphoryl-group transfer from acetyl phosphate to ethanol to make a phosphate ester has to be drawn. 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. It has − C − O − P − linkage. 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. Phosphorylation: The reaction where phosphoryl group ( P O 3 2 − ) of a molecule is transferred to other is known as phosphorylation. Acetyl phosphate is formed when acetic acid and phosphoric acid reacts where the − C = O carbon and P = O phosphorus atom are attached to a same oxygen atom

Lithium ion inhibits the synthesis of inositol trisphosphate by inhibiting a reaction in the breakdown of inositol trisphosphate. Explain this apparent paradox.

A reaction involved in the metabolism of sugars is the splitting of fructose-1,6-diphosphate to give glyceraldehyde-3- phosphate and dihydroxyacetone phosphate. In the living system, this retro-aldol is catalyzed by an enzyme called aldolase; however, it can also be catalyzed by a mild base. Propose a mechanism for the base-catalyzed reaction.
