Question
Answer the following questions.
A non-reducing disaccharide ‘A’ on hydrolysis with dilute acid gives an equimolar mixture of D-(+)-glucose and D-(-)-fructose.
$\text{A}+\text{H}_2\text{O}\xrightarrow{\text{HCl}\ \ \ \ }\ \ \ \ \ \ \text{C}_6\text{H}_{12}\text{O}_6+\ \ \ \ \ \ \text{C}_6\text{H}_{12}\text{O}_6\\ [\alpha]_{\text{D}}=+66.5\hat{\text{O}}\phi\Omega\ \ \ \ \ +52.5\hat{\text{O}}\phi\Omega\ \ \ \ \ -92.4\hat{\text{O}}\phi\Omega$
Identify A. What is the mixture of D-(+)-glucose and D-(-)-fructose known as? Name the linkage that holds the two units in the disaccharide.
