Chapter 23.2, Problem 23.1PP

(a)

Interpretation Introduction

Interpretation:

The products that are formed when $9\text{-phenylnonanoic acid}$ is degraded by $\text{β-oxidation}$ have to be determined.

Concept Introduction:

$\text{β-oxidation}$ is essentially the process of degradation of fatty acid into two-carbon acetyl-CoA. In each cycle of $\text{β-oxidation}$, one fatty acid is converted to acetyl CoA and an acyl derivative of fatty acid with two carbons lesser than the initial fatty acid.

The product formed in $\text{β-oxidation}$ of $\text{ω-phenyl-labeled}$ carboxylic acid that consists of even number of carbon atoms includes phenylacetate and acetate as the products while the corresponding derivatives of acid that contain the odd number of carbon atoms afford benzoate and acetate as products.

(b)

Interpretation Introduction

Interpretation:

The products formed when $\text{8-phenyloctanoic acid }$ is degraded by β-oxidation have to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The products that are formed when $\text{7-phenylheptanoic acid}$ is degraded by $\text{β-oxidation}$ have to be determined.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

The products formed when $\text{12-phenyldodecanoic acid}$ is degraded by β-oxidation have to be determined.

Concept Introduction:

Refer to part (a).
