Question

Identify each of the following as the D or L enantiomer:

Short answer

a) In this example, we have Arabinose, and since the $\mathrm{OH}$group is on the right side, this structure is $\mathbf{D}$enantiomer.

b) In this example, we have Sorbose, and the penultimate OH group is on the left side, which means that this is L-Sorbose.

c) In this example, we have Lyxose, and the penultimate $\mathrm{OH}$group is on the right side, which means that this is $\mathbf{D}$enantiomer.

d) In this example, we have Ribose, and the penultimate $\mathrm{OH}$group is on the left side, which means that this is $L$- Ribose.

Step-by-step solution

Introduction

Carbohydrates are the most abundant class of organic compounds on the planet. Carbohydrates account for over 75% of the dry planet's bulk

Explanation part(a)

In this problem, we have to identify given structures as $D$or $L$enantiomers.

Explanation part(b)

In this problem, we have to identify given structures as $D$or $L$ enantiomers.

Explanation part(c)

In this problem, we have to identify given structures as$D$or$L$enantiomers.

Explanation part(d)

In this problem, we have to identify given structures as$D$or$L$enantiomers.
