Question

Draw the α anomer of maltose. What products are formed on hydrolysis of this form of maltose?

Short answer

Answer

Hydrolysis of $\mathrm{\alpha }$-anomer of maltose

Step-by-step solution

Maltose

The carbohydrate maltose is a disaccharide obtained from starch. It is present in barley. It consists of two glucose units joined by $\mathbf{1}\mathbf{\to }\mathbf{4}\mathbf{}\mathbf{\alpha }$ a glycoside bond.

Anomers

The diastereomers that differ in the configuration at the first carbon are anomers.

Maltose exists in two forms, and they differ in the configuration of the first carbon. That is $\mathbf{\alpha }$anomer and $\mathbf{\beta }$ anomer, and both differ in the configuration at the first carbon.

Hydrolysis products of  -anomer of maltose

The hydrolysis of maltose produces two anomeric forms of glucose. They are $\mathrm{\alpha }$D-glucose and $\mathrm{\beta }$D-glucose. The structures and the reaction are as shown:
