Chapter 18.1, Problem 5PP

Interpretation Introduction

Interpretation: To determine the number and the kind of atoms in the ring portion of the Haworth structure of a D-glucose.

Concept introduction: Monosaccharides are most basic form of a carbohydrate and simplest form of sugars. They are unable to hydrolyze into simpler components. For example D- glucose is a monosaccharide with the chemical formula C₆H₁₂O₆. Since, it has six carbon atoms in its structure it is classified as a hexose, which is a subcategory of monosaccharides. The term D- glucose has been given to the Fischer projection structure of glucose as it determines the orientation of hydroxyl groups in the stereocenter of the glucose. If the hydroxyl group is present to the right of the last stereocenter in the structure, then it is referred to as D-Glucose. A Haworth structure is a common way to write the structural formula of a given monosaccharide in the cyclic form with a simple 3-D perspective.
