Q. 15.13 - An Introduction to General, Organic, and Biological Chemistry

Question

Compare the structures and functional groups of arachidonic acid and prostaglandin ${\mathrm{PGE}}_1$.

Step-by-Step Solution

Answer

1. Four carbons - carbon double bonds are present in arachidonic acid.

2. No carbon ring is present in arachidonic acid.

3. Just one carbon - carbon double bond is prostaglandin. 

4. Cyclopentane ring is present in ${\mathrm{PGE}}_1$.

Step 1: Given Information

The structures and functional groups of arachidonic acid and prostaglandin ${\mathrm{PGE}}_1$.

Step 2: An Introduction

Polyunsaturated fatty acids contained in animal fats. It is important for metabolism, especially for the synthesis of prostaglandins and leukotrienes, and is an important part of the diet.

Step 3: Determine the structures and functional groups of arachidonic acid.

 Four carbons - carbon double bonds are present in arachidonic acid.

 No carbon ring is present in arachidonic acid.

Step 4: Determine the structures and functional groups of and prostaglandin PGE 1 .

Just one carbon - carbon double bond is prostaglandin. 

Cyclopentane ring is present in ${\mathrm{PGE}}_1$.
