(a) Interpretation: The given Haworth projection should be converted into an open-chain form and to Fischer projections. Also, name the monosaccharide so formed. Concept Introduction: A Haworth projection is a way to write structral fornula that reprsents the cyclic structure of a monosaccharide. There are following characteristics a Haworth projection should have: In the Haworth projection, for six carbon atoms, the atoms are numbered from 1 to 6 and carbon 1 is known as anomeric carbon. The ticker line denotes the atoms closer to the observer and thiner lines denotes the atoms away from the observer. The Fischer projection is two dimensional representation of the three-dimensional projection. It is used to differentiate between D and L molecules. In the D configuration, the carbon next to the last has hydrogen on the left and hydroxyl group on the right whereas in L configuration, the hydrogen is on the right a hydroxyl group on the left. All the horizontal bonds in the Fischer projection are directed towards the viewer and vertical bonds are directed away from the viewer.

Interpretation Introduction

(a)

Interpretation:

The given Haworth projection should be converted into an open-chain form and to Fischer projections. Also, name the monosaccharide so formed.

Concept Introduction:

A Haworth projection is a way to write structral fornula that reprsents the cyclic structure of a monosaccharide. There are following characteristics a Haworth projection should have:

In the Haworth projection, for six carbon atoms, the atoms are numbered from 1 to 6 and carbon 1 is known as anomeric carbon. The ticker line denotes the atoms closer to the observer and thiner lines denotes the atoms away from the observer.

The Fischer projection is two dimensional representation of the three-dimensional projection. It is used to differentiate between D and L molecules. In the D configuration, the carbon next to the last has hydrogen on the left and hydroxyl group on the right whereas in L configuration, the hydrogen is on the right a hydroxyl group on the left.

All the horizontal bonds in the Fischer projection are directed towards the viewer and vertical bonds are directed away from the viewer.
