Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides:
Disaccharide = monosaccharide + monosaccharide
Sucrose = glucose + fructose
Lactose = glucose + </span>galactose
Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
