The answer is Disaccharides are different in structure because they are not made up of the same monosaccharides, and this gives them different properties.

Both sucrose and lactose are disaccharides, however, they are made up different monosaccharides:

Disaccharide = monosaccharide + monosaccharide

Sucrose = glucose + fructose

Lactose = glucose + galactose

Since they have different structures, their characteristics and behaviour in chemical reactions must differ, too.
