Chapter 22, Problem 26P

Interpretation Introduction

Interpretation:

The structures of D –- psicose and D –- tagatose are to be shown.

Concept Introduction:

▸ Monosaccharides, fructose, sorbose, psicose and tagatose are ketohexoses. Monosaccharides allose and galactose are aldohexoses. All of them are reducing sugars.

▸ Compounds formed by the reaction of reducing sugars with excess of phenylhydrazine are called osazones. Osazones are products of oxidation and are produced by all of the reducing sugars.

▸ The Fischer projection is a way of representing biomolecules with cross formulation of the open chain structures of $\text{D}-\text{Glucose}$.
