Chapter 28, Problem 28.42P

Interpretation Introduction

(a)

Interpretation: The enantiomer of D-arabinose is to be drawn.

Concept introduction: An arabinose is a monosaccharide which contains five carbon atoms and an aldehyde group. The molecular formula of arabinose is ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}{\text{O}}_{\text{5}}$.

Interpretation Introduction

(b)

Interpretation: An epimer of D-arabinose at ${\text{C}}_{\text{3}}$ is to be drawn.

Concept introduction: An arabinose is a monosaccharide which contains five carbon atoms and an aldehyde group. The molecular formula of arabinose is ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}{\text{O}}_{\text{5}}$.

Interpretation Introduction

(c)

Interpretation: The diastereomer that is not an epimer of D-arabinose is to be drawn.

Concept introduction: An arabinose is a monosaccharide which contains five carbon atoms and an aldehyde group. The molecular formula of arabinose is ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}{\text{O}}_{\text{5}}$.

Interpretation Introduction

(d)

Interpretation: The constitutional isomer of D-arabinose contains a carbonyl group is to be drawn.

Concept introduction: An arabinose is a monosaccharide which contains five carbon atoms and an aldehyde group. The molecular formula of arabinose is ${\text{C}}_{\text{5}}{\text{H}}_{\text{10}}{\text{O}}_{\text{5}}$.
