    Sugar is sucrose which has a formula C12H22O11. In biology 課本講過兩個單糖 (monosaccharide, formula is C6H12O6) 會 combine to form a disaccharide (雙糖). Sucrose is made up of one glucose (C6H12O6) and one fructose (C6H12O6).

    C6H12O6 + C6H12O6 -----> C12H22O11 + H2O

    glucose + fructose ---------> sucrose + water
