If it is added to a sample that contains starch, such as the bread pictured above, the color changes to a deep blue. But how does this color change work?
Iodine Test for Polysaccharides 2.0 YouTube
The main biological function of iodine concerns its role in the biosynthesis of thyroid hormones (THs) by the thyroid gland. In addition, however, further biological roles of iodine have emerged. Precisely, due to its significant action as scavenger of reactive oxygen species (ROS), iodine is thought to represent one of the oldest antioxidants.

Principle Of Iodine Test. This test depends upon the property of adsorption possessed by the large polysaccharide molecules. Starch contains alpha-amylose, helical saccharide polymer and amylopectin. Triiodide anion instantly produces an intense blue-black color upon contact with starch. This reaction is as a result of the formation of.
