In which of the following disaccharides both the basic structural units are the same?
Correct answer: B. Maltose
- A. Lactose
- B. Maltose
- C. Sucrose
- D. All of the above
Explanation
Maltose is composed of two glucose molecules bonded together. In contrast, lactose consists of one glucose molecule and one galactose molecule, while sucrose is made up of one glucose molecule and one fructose molecule. So, maltose is the disaccharide where both structural units are the same.
