A Comparison of Periodic Acid-Schiff Staining With Lugol’s Iodine for the Detection of Vaginal Fluid in Dried Material

SOLVED: Title: Iodine Test for StarchStaining by iodine (iodine-potassium iodide, KI) distinguishes starch from monosaccharides, disaccharides, and other polysaccharides. The basis for this test is that starch is a polymer of glucose; iodine interacts with these coiled molecules and becomes bluish black. Iodine does not react with carbohydrates that are not coiled and remains yellowish brown. Therefore, a bluish-black color is a positive test for starch, and a yellowish-brown color is a negative
