Chapter 15, Problem 15.26EP

(a)

Interpretation Introduction

Interpretation: To identify whether glutamate is an amino acid or not.

Concept introduction: Amino acids are the biomolecules which contain an amino group, carboxylic acid group, and an alkyl chain. Amino acid combines to form a polypeptide chain joined via a peptide bond $\left(-\text{CO}-{\text{NH}}_{\text{2}}-\right)$.

The general structure of an amino acid is:

Here, $\text{R}$ is the side chain which is different for a different amino acid.

(b)

Interpretation Introduction

Interpretation: To identify whether oxaloacetate is an amino acid or not.

Concept introduction: Amino acids are the biomolecules which contain an amino group, carboxylic acid group, and an alkyl chain. Amino acid combines to form a polypeptide chain joined via a peptide bond $\left(-\text{CO}-{\text{NH}}_{\text{2}}-\right)$.

The general structure of an amino acid is:

Here, $\text{R}$ is the side chain which is different for a different amino acid.

(c)

Interpretation Introduction

Interpretation: To identify whether $\text{α-Ketoglutarate}$ is an amino acid or not.

Concept introduction: Amino acids are the biomolecules which contain an amino group, carboxylic acid group, and an alkyl chain. Amino acid combines to form a polypeptide chain joined via a peptide bond $\left(-\text{CO}-{\text{NH}}_{\text{2}}-\right)$.

The general structure of an amino acid is:

Here, $\text{R}$ is the side chain which is different for a different amino acid.

(d)

Interpretation Introduction

Interpretation: To identify whether succinate is an amino acid or not.

Concept introduction: Amino acids are the biomolecules which contain an amino group, carboxylic acid group, and an alkyl chain. Amino acid combines to form a polypeptide chain joined via a peptide bond $\left(-\text{CO}-{\text{NH}}_{\text{2}}-\right)$.

The general structure of an amino acid is:

Here, $\text{R}$ is the side chain which is different for a different amino acid.
