Chapter 18.3, Problem 18.4Q

(a)

Interpretation Introduction

Interpretation:

The structure of the glycyl-valyl-serine peptide at pH 7 has to be written.

Concept Introduction:

Peptides are the compounds that consist of amide linkage and formed when the carboxylic acid of one unit of amino acid reacts with the amine group of another amino acid. The amide linkage is also therefore known as peptide linkage.

Steps to draw the structure of the peptide is as follows:

Step 1: The backbone of the given peptide is to be written in which a three atom set (NCC) can be used to represent a backbone of amino acid. The backbone is started from N-terminal to C-terminal.

Step 2 Oxygen atoms are to be added to the carbonyl carbon and hydrogen atoms to the amino nitrogens.

Step 3: One hydrogen atom should be added on each alpha-carbon atom.

Step 4: Then respective side chain on respective alpha carbon is to be added.

(b)

Interpretation Introduction

Interpretation:

The structure of the threonyl-cysteine peptide at pH 7 has to be written.

Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH,CN H₂O B 88 C Use these sketches to answer the questions in the table below. The enthalpy of solution AH is negative soln when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage C to D? What force would oppose or favor the system moving from Stage C to D? Check all that apply. 1 absorbed O released neither absorbed nor released. none O ionic bonding force covalent bonding force…
In a system with an anodic overpotential, the variation of ŋ as a function of the current density: 1. at low fields is linear 2. at higher fields, it follows Tafel's law Find the range of current densities for which the overpotential has the same value as when calculated for cases 1 and 2 (maximum relative difference of 5% with respect to the behavior for higher fields). To which overpotential range does this correspond? Data: 10 = 1.5 mA cm², T = 300°C, ẞ = 0.64, R = 8.314 J K 1 mol‍¹ and F = 96485 C mol-1.
