I will do this by looking in more depth at their structures, bond type etc ... Polysaccharides are complex carbohydrates. A polysaccharide is made up of lots of monosaccharides joined together in a large chain by glycosidic bonds. Glycosidic bonds are covalent and form after a condensation reaction. They have a very large relative atomic mass, and can either be branched or unbranched. Unlike monosaccharides and disaccharides they do not taste sweet and they are also insoluble. Polysaccharides have a general formula of Cn(H2O)n-1 where n is usually a large number between 200 and 500. Starch is a polysaccharide made up of alpha glucose monosaccharides. However the alpha glucose in starch forms two compounds; amylopectin and amlylose. Amylopectin makes up 70 % of starch, it consists of chains of glucose monomers...
