Chapter 18.4, Problem 6P
Interpretation Introduction

Interpretation:

The reason for why mannose is one of the products when glucose undergoes base-catalyzed isomerization in the absence of an enzyme whereas mannose is not formed in the presence of an enzyme catalyzed reaction has to be explained

Concept introduction:

  • Enzyme is a protein that is a biological catalyst. The reactant in a reaction catalyzed by the enzyme is called substrate. In the enzyme, a pocket like cleft is present called active site where it binds the substrate.
  • Some amino acid chains in the enzyme act as base, acid and nucleophilic catalyst. Many of the enzymes contain metal ions at the active site which acts as catalyst.
  • Acid Catalyst helps in increasing the rate of a particular reaction by the donation of a proton to substrate.
  • Base Catalyst helps in increasing the rate of a particular reaction by the removal of a proton to substrate.
  • Nucleophilic catalysis helps in increasing the rate of a particular reaction by the formation of a covalent bond with substrate
  • Glycolysis: A series of reactions where glucose is converted to two pyruvate molecules in the presence of enzymes catalysis.

a. The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 " is best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: HO + :Ö: Bicarbonate is crucial for the control of body pH (for example, blood pH 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.
