What molecule is larger starch or sugar?
Starch is a storage polysaccharide and is therefore much larger than sugar, which is merely carbohydrate molecules. Starch is composed of long chains of glucose monomers linked to one another through different types of linkages. Starch shows a branched structure composed of two components: amylose and amylopectin, both of which are basically chains of glucose units. They way in which they are linked to one another decides their properties.
