Chapter 23.10, Problem 23.23P

Interpretation Introduction

Interpretation:

Amino acid that contains aromatic ring, sulfur, alcohols, and alkyl side chaines has to be determined.

Concept Introduction:

• Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.
• Amino acid had both amino functional group and carboxyl functional group in a molecule.
• Amino functional group is $(-N{H}_2)$ and carboxyl functional group is $(-COOH)$ and a $R$ group is considered as side chain, when all these are bonded to same carbon atom.
• Aromatic ring is known to be arenes that contains one or more benzene-like rings.
• Side chain in amino acids can have sulfur in its structure.
• Side chain which have pure hydrocarbon alkyl groups(alkane branches).
• Alcohols have $-OH$ as the functional group.
