The iodine test can help to distinguish starch from monosaccharides, disaccharides, and other polysaccharides. The iodine test is used for distinguishing between starch, glycogen, and carbohydrates. Principle of Iodine test The basic principle involved in the iodine test is that Amylose interacts with starch to form a blue-black colored complex with the iodine. The helical structure of Amylose forms a charge transfer (CT) complex with iodine, wherein iodine is present inside the spiral or helical structure of the Amylose Iodine - KI Reagent: Iodine is not very soluble in water, therefore the iodine reagent is made by dissolving iodine in water in the presence of potassium iodide. This makes a linear triiodide ion complex with is soluble and slips into the coil of the starch causing an intense blue-black color. Procedure 1. Take 1 ml of a given sample in a clean, dry test tube. 2. Add about 2-3 drops of Iodine solution to the tube and mix them. 3. Observe the appearance of color in the test tubes. 4. If there is the appearance of a blue colour then the presence of starch is confirmed Get in touch with the solution by just clicking the following links- Facebook Group- https://www.facebook.com/groups/solutionpharamcy Mobile App - https://play.google.com/store/apps/details?id=co.bolton.nqilv New Channel (Pharmacy Dictionary) https://www.youtube.com/channel/UCt6OXVV_2oxf5DD0Mad6e9A E-Mail for official and other work - solutionpharmacy@gmail.com
