Chapter 18.3, Problem 18.3P

Interpretation Introduction

Interpretation:

Structure of alanine has to be drawn, label the functional groups, three letter and one letter abbreviation has to be given and the group that side chain fall into has to be identified.

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.

Each amino acid can be represented by both three letter short hand code as well as one letter code.
