A dehydration reaction links two glucose molecules to produce maltose. If the formula for glucose is C6H12O6 then what is the formula for maltose?
- C12H20O10
- C12H24O12
- C12H22O11
- C12H24O11
Answer
(3) C12H22O11
Solution
Two glucose units are joined by a glycosidic bond formed by dehydration, i.e. one molecule of water is removed.
2 C6H12O6 - H2O = C12H22O11
Maltose = C12H22O11
Answer: (3)
