(a)

Interpretation Introduction

Interpretation:

The nature of inhibition shown by phenylthiourea has to be determined.

Concept Introduction:

Certain inhibitors may compete to bind at the active site of the enzyme as they resemble the structure of the natural substrate of that particular enzyme. They may occupy the active site for a transient period of time as they are held by only weak forces and thus dissociate quickly. They are termed as reversible competitive inhibitors. Unlike the case of irreversible inhibition they are bound strongly via covalent interaction that does not allow the inhibitor to dissociate from the active site. The significance of such inhibition is that it can be reversed if the natural substrate can be bound to the enzyme with stronger forces or if the concentration of the natural substrate is increased.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule

In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction. Click and drag to start drawing a structure. ☐ : A ค

Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х а
