During transpeptidation, nucleophilic attack occurs between the α-amine group in the ____ site and the esterified carbon in the
kobusy [5.1K]

During transpeptidation, nucleophilic attack occurs between the α-amine group in the A site and the esterified carbon in the P site

<h3>What is transpeptidation ?</h3>

A chemical process in which an amino acid residue or peptide residue is transferred from one amino compound to another. This process occurs when a protease reversibly converts one peptide to another.

  • a process where one or more amino acids are transferred from one peptide chain to another, as in the case of a transpeptidase activity, or where a peptide chain itself is produced, as in the case of the production of a bacterial cell wall.
  • Peptidoglycan glyco-syltransferases create the glycan strands (PGTs). The most popular class of antibiotics' fatal targets are enzymes termed transpeptidases (TPs), which produce the peptide crosslinks: using beta-lactams

Find the enthalpy of neutralization of HCl and NaOH. 137 cm3 of 2.6 mol dm-3 hydrochloric acid was neutralized by 137 cm3 of 2.6
Lerok [7]

Answer:

Approximately \rm -89 \; kJ\cdot mol^{-1}.

Assumption: the density of the solution is equal to the density of pure water.

Explanation:

The enthalpy of neutralization is defined as the enthalpy change for each moles of water produced. (Clark, Physical & Theoretical Chemistry, Chemistry Libretexts.)

Each mole of \rm NaOH formula units will neutralize one mole of \rm HCl to produce one mole of water. \rm HCl and \rm NaOH are available at equal volume and concentration. In other words, there's an equal number of both reactants. All \rm HCl and \rm NaOH will react to form water.

V(\mathrm{HCl}) = \rm 137\; cm^{3} = 0.137\;dm^{3}.

V(\mathrm{NaOH}) = \rm 137\; cm^{3} = 0.137\;dm^{3}.

n = c\cdot V = \rm 0.137\;dm^{3} \times 2.6\;mol\cdot dm^{-3} = 0.3652\; mol.

In other words, there are \rm 0.3652\; mol of \rm HCl and \rm NaOH each. The two will react to produce \rm 0.3652\; mol of water.

How much heat is released?

Assume that the volume of the liquid is equal to the volume of the \rm HCl solution plus the volume of the \rm NaOH solution. That's \rm 0.274\;dm^{3}. Assume that the density of the solution is equal to that of water under room temperature. \rho(\text{water}) = \rm 1.000\; kg\cdot dm^{-3}. The mass of the liquid will be m = \rho \cdot V = \rm 0.274\; dm^{3} \times 1.000\; kg\cdot dm^{-3} = 0.274\; kg = 274\;g.

Change in temperature:

\Delta T = \rm 325.8 - 298 = 27.8\; K.

Heat that the solution absorbed:

Q = c\cdot m \cdot \Delta T = \rm 4.18\;J\cdot K^{-1}\cdot g^{-1} \times 274\; g\times 27.8\;K = 36410.216\; J = 36.410216\; kJ.

That will also be the amount of heat released from the reaction if there's no energy loss.

\displaystyle \Delta H(\text{Neutralization}) = \frac{-Q}{n(\text{water produced})} = \rm \frac{36.410216\; kJ}{0.3652\; mol} \approx 89\; kJ\cdot mol^{-1}.
