Carbohydrates and lipids — practice question

Maltose and sucrose are two disaccharides. Maltose is made from two glucose molecules, whereas sucrose is made from glucose and fructose. Which row gives the molecular formulae of these two disaccharides?

  • Amaltose $\text{C}_{12}\text{H}_{22}\text{O}_{11}$; sucrose $\text{C}_{12}\text{H}_{22}\text{O}_{11}$
  • Bmaltose $\text{C}_{12}\text{H}_{22}\text{O}_{11}$; sucrose $\text{C}_{12}\text{H}_{24}\text{O}_{12}$
  • Cmaltose $\text{C}_{12}\text{H}_{24}\text{O}_{12}$; sucrose $\text{C}_{12}\text{H}_{22}\text{O}_{11}$
  • Dmaltose $\text{C}_{12}\text{H}_{24}\text{O}_{12}$; sucrose $\text{C}_{12}\text{H}_{24}\text{O}_{12}$
