Know about polysaccharides Describe the structure of starch (amylose & amylopectin), glycogen and cellulose Explain how the structure and properties of glucose, starch, glycogen and cellulose relate to their functions in living organisms Describe how to carry out the non-reducing sugars test. WebbStarch is often used in chemistry as an indicator for redox titrations where triiodide is present. [1] Starch forms a very dark blue-black complex with triiodide. However, the complex is not formed if only iodine or only iodide (I −) is present.
