Carbohydrates and lipids — practice question

Which reaction shows one correct way that sucrose can be formed?

  • A$(\alpha\text{-glucose} - \text{OH}^-) + (\text{fructose} - \text{H}^+) \rightarrow \text{sucrose} + \text{H}_2\text{O}$
  • B$(\alpha\text{-glucose} + \text{OH}^-) + (\alpha\text{-glucose} + \text{H}^+) \rightarrow \text{sucrose} - \text{H}_2\text{O}$
  • C$(\alpha\text{-glucose} - \text{OH}^-) + (\beta\text{-glucose} - \text{H}^+) \rightarrow \text{sucrose} + \text{H}_2\text{O}$
  • D$(\alpha\text{-glucose} + \text{OH}^-) + (\text{fructose} + \text{H}^+) \rightarrow \text{sucrose} - \text{H}_2\text{O}$
