Iodine indicates the presence of starch in a solution by altering the energy level spacing in the amylose component of starch, creating an intense blue color. This energy change allows amylose to absorb visible light.

When iodine and starch interact, iodine molecules become arranged within the starch molecules in a linear fashion. The visible end result of this arrangement is the appearance of a blue-black coloration.

Iodine reacts with starch in water to produce an intensely blue color. Beta amylose, which is a form of soluble starch, traps iodine ions within its highly coiled structure to achieve this effect.

Iodine stains starch because of the chemical reaction between it and the polysaccharides in starch molecules. This reaction turns the starch a deep blue hue. This phenomenon is called Lugol's reaction for starch. Iodine is useful in laboratories and medical offices because it also reacts with many o

Starch when mixed with Iodine turns a deep shade of blue because starch contains amylose. Amylose is a soluble component of starch as well as other carbohydrates.

Starch has the largest molecule out of all of starch, iodine and water. This is because it is composed of numerous units of glucose, so it's technically a polymer.

Iodine is a pure element, whereas iodide is an anion attached to molecules made from iodine, including potassium iodide, sodium iodide and methyl iodide. Iodide has a negative charge of one. The pure element has the chemical symbol "I" on the periodic table of elements, and the anion has a minus sig

White rice, cornmeal and white potatoes are the three foods with the highest levels of starch. Just one serving of white rice (parboiled, cooked and unenriched) has 47 grams of starch. These types of foods generally digest in a very short time and cause blood sugar levels to spike.

Starch in food plays an important role in the metabolic process. Starch is a carbohydrate that aids in the conversion of glucose to energy. Many vegetables are high in starch, including corn, potatoes and squash. Starch can also be added to the diet by consuming whole wheat bread.

Cellulose and starch are two similar polymers, but the main difference between them is humans can eat starch but are not able to digest cellulose. Humans have enzymes that break down starch into glucose that the body uses as fuel, but the body has no enzymes that break down cellulose.
