Question

What are the functional groups included in maltose's structure?

• A. One acetal and one hemiacetal
• B. One acetal and one ketal
• C. One ketal and one hemiketal
• D. Two acetals

Answer 1

The correct option is A

One acetal and one hemiacetal

The explanation for the correct option:

A: One acetal and one hemiacetal

Maltose:

• Maltose is made up of two glucose molecules. A molecule of Water $\left({\mathrm{H}}_2\mathrm{O}\right)$ is eliminated when the two molecules join together.
• Diastase is used to make maltose, or malt sugar, which has the formula $({\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}.{\mathrm{H}}_2\mathrm{O})$.
• Only d-glucose is produced by acid or maltose hydrolysis.
• There is no added sugar in the lean dough since the majority of the sugar accessible to yeast is maltose, which is generated from starch.
• Maltose behaves more like a photosynthetic early product than a storage product like starch and its breakdown products.

Structure of Maltose:

Final Answer: Therefore, option A is the correct answer.
