Chapter 6, Problem 6.22PP

Summary Introduction

To draw:

The $\alpha$ and $\beta$ anomer of D-altrose in pyranose ring form.

Introduction:

Altrose is an aldohexose sugar, which is soluble in water and slightly in methanol. Molecular formula of altrose sugar is ${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}$. The molecular mass is $\text{180}\text{.16 g/mol}$ . Anomers are the distereo-isomers of cyclic forms of sugars. The cyclic forms of the sugar sugar can exist in two forms $\alpha$ and $\beta$, based on the position of the anomeric carbon.
