Amongst these the most common are disaccharides The two monosaccharide units obtained on hydrolysis of a disaccharide
may be same or different For example, one molecule of sucrose on
hydrolysis gives one molecule of glucose and  one molecule of fructose
whereas maltose gives two molecules of  only glucose (iii) Polysaccharides: Carbohydrates which yield a large number of
monosaccharide units on hydrolysis are called polysaccharides
