Chapter 18.8, Problem 15P

Interpretation Introduction

Interpretation:

The hydrogen of the $\text{C-8}$ methyl group is more acidic than those of the $\text{C-7}$ methyl group.  This is has to be explained.

Concept introduction:

${\text{NAD}}^{\text{+}}$ and $\text{NADH}$ are the coenzymes associated with catabolic reactions- biological reactions that break down complex bio molecules in order to provide the cell with energy .  Catabolic reactions are predominately oxidation reaction.  ${\text{NAD}}^{\text{+}}$ is the most common oxidizing agent in cells.

${\text{NAD}}^{\text{+}}$ and $\text{NADPH}$ are the coenzymes associated with Anabolic reactions- biological reactions involved in synthesizing complex bio molecules.  Anabolic reactions are predominantly reduction.  Catabolic reactions are predominately oxidation reaction.  $\text{NADPH}$ is the most common reducing agent in cells.

$\text{FAD}$ Catalyses oxidation reaction; it is reducing to ${\text{FADH}}_2$
