Chapter 18.4, Problem 18.37QAP

Interpretation Introduction

(a)

Interpretation:

The name of an amino acid with the three-letter abbreviation Ala needs to be identified.

Concept Introduction:

The amino acid consists of two functional groups that is amino group as well as carboxylic acid group. There are 20 essential amino acids which are different from each other due to the different R group attached to the carbon containing amino as well as carboxyl groups. The amino acids can be named using the three and one-letter abbreviations.

The three-letter abbreviation is generally done by taking first three letters from its name.

For example, the three letter and one letter abbreviations of some of the amino acids is as follows:

Arginine-Arg and R

Asparagine-Asn and N

Aspartic acid-Asp and D

Interpretation Introduction

(b)

Interpretation:

The name of an amino acid with the one-letter abbreviation V needs to be identified.

Concept Introduction:

The amino acid consists of two functional groups that is amino group as well as carboxylic acid group. There are 20 essential amino acids which are different from each other due to the different R group attached to the carbon containing amino as well as carboxyl groups. The amino acids can be named using the three and one-letter abbreviations.

The three-letter abbreviation is generally done by taking first three letters from its name.

For example, the three letter and one letter abbreviations of some of the amino acids is as follows:

Arginine-Arg and R

Interpretation Introduction

(c)

Interpretation:

The name of an amino acid with the three-letter abbreviation Lys needs to be identified.

(d)

Interpretation:

The name of an amino acid with the one-letter abbreviation C needs to be identified.
