Chapter 15, Problem 15.103EP

(a)

Interpretation Introduction

Interpretation: To identify whether citrulline is encountered in the (1) urea cycle, (2) heme degradation process, or (3) oxidative deamination reaction.

Concept introduction: A urea cycle is a cyclic biochemical pathway that involves the production of urea using ammonium ions and aspartate molecules as nitrogen sources. The desired product of the urea cycle is urea.

Heme potion of hemoglobin undergoes a stepwise degradation to biliverdin, to bilirubin, and then to bile pigments that are excreted from the body.

A biochemical reaction in which an α-amino acid is converted into α-keto acid along with the release of an ammonium ion is known as oxidative deamination reaction. A general oxidative deamination reaction is as follows:

α-amino acid+NAD++H2Oα-keto acid+NH4++NADH+H+

(b)

Interpretation Introduction

Interpretation: To identify whether glutamate is encountered in the (1) urea cycle, (2) heme degradation process, or (3) oxidative deamination reaction.

A biochemical reaction in which an α-amino acid is converted into α-keto acid along with the release of an ammonium ion is known as oxidative deamination reaction. A general oxidative deamination reaction is as follows:

α-amino acid+NAD++H2Oα-keto acid+NH4++NADH+H+

Below is the SN1 reaction of (S)-3-chlorocyclohexene and hydroxide (OH). Draw the missing curved arrows, lone pairs of electrons, and nonzero formal charges. In the third box, draw the two enantiomeric products that will be produced. 5th attempt Please draw all four bonds at chiral centers. Draw the two enantiomeric products that will be produced. Draw in any hydrogen at chiral centers. 1000 4th attempt Feedback Please draw all four bonds at chiral centers. 8. R5 HO: See Periodic Table See Hint H Cl Br Jid See Periodic Table See Hint
Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.
(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
