The bonding in disulfide bonds present in protein chains has to be described in terms of hybridization.

Question

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol.

(a)

Interpretation Introduction

Interpretation:

The bonding in disulfide bonds present in protein chains has to be described in terms of hybridization.

(b)

Interpretation Introduction

Interpretation:

From the given list of amino acids in table 25.2 of the text book, the amino acid that contains −SH group has to be has to be identified.

(c)

Interpretation Introduction

Interpretation:

The signs of ΔS and ΔH have to be predicted for denaturation process.

Concept Introduction:

Entropy refers to measurement of randomness or disorderliness in the system. More the number of molecules in a system more will be the movement of molecules and greater will be the entropy given that weak intermolecular forces prevails between molecules.

Entropy is denoted by ‘S’ and ΔS° refers to change in entropy of the system. ΔS° value positive for a phenomenon indicates the process is spontaneous. ΔS° value negative for a phenomenon indicates the process is non–spontaneous

The term free energy G, refers to energy available in the system to do work and enthalpy H, refers to heat content of the system. Change in standard free energy is ΔG° and change in standard enthalpy is ΔH°.

All these three parameters are related by an equation,

ΔG°=ΔH°−TΔS°

Standard free energy change, ΔG°, is represented as,

ΔG°=ΔH°−TΔS°

Where,

ΔH° = standard enthalpy changeΔS° = standard entropy change

Spontaneous process has – positive entropy value and negative free energy, enthalpy value.

Non-spontaneous process tends to proceed with negative entropy value and positive free energy and enthalpy.

(d)

Interpretation Introduction

Interpretation:

The fraction of regenerated protein structure that correspond to native form has to be calculated if formation of disulfide bond is random between two SH groups by oxidation.

(e)

Interpretation Introduction

Interpretation:

The chemical basis for the reaction involving in deodorizing a dog with hydrogen peroxide solution has to be explained.
