Chapter 24, Problem 24.8P

Interpretation Introduction

(a)

Interpretation:

The name of the aldose is to be stated. The Fischer projection of the aldose is to be drawn.

Concept introduction:

Aldose is a carbohydrate which contains an aldehyde group. Furanose is the cyclic form of the aldose which consists of a five-membered ring made up of four carbon atoms and one oxygen atom. The furanose ring is substituted with hydroxy groups, hydrogen atoms, and a ${\text{CH}}_{\text{2}}\text{OH}$ group. Fischer projections is a two dimensional representation of organic compounds. It was proposed to represent glucose molecules.

Interpretation Introduction

(b)

Interpretation:

The name of the aldose is to be stated. The carbons which have same and different configuration from glucose are to be identified.

Concept introduction:

Aldose is a carbohydrate which contains an aldehyde group. Pyranose is the cyclic form of the aldose which consists of a six-membered ring made up of four carbon atoms and one oxygen atom. The pyranose ring is substituted with hydroxy groups, hydrogen atoms, and a ${\text{CH}}_{\text{2}}\text{OH}$ group.

Interpretation Introduction

(c)

Interpretation:

The name of the aldose is to be stated. The Fischer projection of the aldose is to be drawn.

Concept introduction:

Aldose is a carbohydrate which contains an aldehyde group. Furanose is the cyclic form of the aldose which consists of a five-membered ring made up of four carbon atoms and one oxygen atom. The furanose ring is substituted with hydroxy groups, hydrogen atoms, and a ${\text{CH}}_{\text{2}}\text{OH}$ group. The carbon atom adjacent to the oxygen atom which is substituted by the hydroxyl group is known as anomeric carbon.
