Chapter 22, Problem 18TE
The chemical compound lysine is shown below. What functional group must be removed in order to produce cadaverine, as shown in figure 22.11?
Expert Solution & Answer
To determine
The group to be removed from Lysine to form Cadaverine.
Answer to Problem 18TE
When we remove the carboxylic acid from Lysine, Cadaverine is formed. The removal of carboxylic group is known as decarboxylation.
Explanation of Solution
Decarboxylation is reaction in which removal of carboxyl group takes place in form of carbon dioxide. This reaction is used to remove a carbon atom from organic compound having a functional group. Lysine contains carboxylic group which has to be removed to form cadaverine This takes by simply heating the lysine molecule so carboxylic group leaves as carbon dioxide Cadaverine is a diamine named as 1,5-pentanediamine and pentamethylenediamine. The structure of Cadaverine is given below-
Conclusion:
Therefore, after the removal of the carbon dioxide form Lysine, Cadaverine is formed.

The abstract should be a short paragraph that very briefly includes the experiment objective, method, result and conclusion. After skimming the abstract, the reader should be able to decide whether they want to keep reading your work. Both the format of the report and the error analysis are to be followed.
