Diphenylamine test for ribose
WebThe Dische’s Test will detect the deoxyribose of DNA and will not interact with the ribose in RNA. The amount of blue corresponds to the amount of DNA in solution. The … WebTest for Complex Carbohydrates (Polysaccharides) Carbohydrates such as starch are detected by mixing a sample with 2–4 drops of iodine or Lugol's solution. The solution will turn from a yellow-brown color to a dark purple if starch is present. The color change is due a chemical reaction bewteen the large carbohydrate molecule and the iodine ions.
