Question

Which of these describes the result of the bonding of two glucose molecules?

• A. A disaccharide of sucrose is formed through the process of hydrolysis.
• B. A disaccharide of maltose is formed through the process of dehydration synthesis.
• C. A polysaccharide of starch is formed through the process of dehydration synthesis.
• D. A disaccharide of galactose is formed through the process of dehydration synthesis.
• E. A polysaccharide of fructose is formed through the process of hydrolysis.

Answer 1

The correct option is B A disaccharide of maltose is formed through the process of dehydration synthesis.

When two glucose molecules bind, a glycosidic bond is formed with the loss of one water molecule and a disaccharide of maltose is formed. Since there is loss of a water molecule, hence it is a dehydration reaction. The reaction is shown in the figure.

So, the correct answer is 'A disaccharide of maltose is formed through the process of dehydration synthesis.'.
