Chapter 24, Problem 13PP

Practice Problem 24.13

The synthesis of a polypeptide containing lysine requires the protection of both amino groups.

(a) Show how you might do this in a synthesis of the dipeptide KI using the ben-zyloxycarbonyl group as a protecting group.

(b) The benzyloxycarbonyl group can also be used to protect the guanidino group, N H | | N H C N H 2 , of arginine. Show a synthesis of the dipeptide RA.

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.
