Chapter 17, Problem 34a
Consider the following unnatural amino acid:
a. If two molecules react to form an ester, what is the structure of the ester product?
Verified step by step guidance1
Identify the functional groups in the unnatural amino acid. Look for the carboxylic acid group (-COOH) and the alcohol group (-OH), as these are the groups involved in ester formation.
Understand the reaction mechanism: Esterification occurs when a carboxylic acid reacts with an alcohol, typically in the presence of an acid catalyst, to form an ester and water.
Determine which parts of the molecule will react: The hydroxyl group (-OH) from the carboxylic acid and the hydrogen atom from the alcohol group will combine to form water (H₂O), leaving the remaining parts to form the ester bond.
Draw the structure of the ester product: Replace the -OH group of the carboxylic acid with the alkoxy group (-OR) from the alcohol. Ensure the ester bond (-COOR) is correctly formed.
Verify the product: Double-check that the ester structure is correct, with the carbonyl carbon (C=O) bonded to the oxygen atom of the alcohol group, and ensure no atoms are missing or incorrectly placed.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Amino Acids
Amino acids are organic compounds that serve as the building blocks of proteins. They contain an amino group, a carboxyl group, and a unique side chain (R group) that determines their properties. Understanding the structure and reactivity of amino acids is crucial for predicting the outcomes of chemical reactions involving them, such as esterification.

Esterification
Esterification is a chemical reaction between an alcohol and a carboxylic acid, resulting in the formation of an ester and water. In the context of amino acids, this process involves the reaction of the carboxyl group of one amino acid with the hydroxyl group of another, leading to the formation of a covalent bond. Recognizing the mechanism of esterification is essential for determining the structure of the resulting ester product.

Chemical Structure Representation
Chemical structure representation involves depicting the arrangement of atoms within a molecule, including bonds and functional groups. This is vital for visualizing how molecules interact during chemical reactions. In the case of the ester product formed from the reaction of two amino acids, accurately representing its structure helps in understanding its properties and potential applications.
