It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen stores in skeletal muscle fill in as a type of vitality stockpiling for the muscle itself; be that as it may, the breakdown of muscle glycogen blocks muscle glucose take-up from the blood, accordingly expanding the measure of blood glucose accessible for use in other tissues. Starch is a glucose polymer in which all repeat units are directed in one direction and connected by alpha bonds. These chemical bonds are formed when glucose undergoes a chemical reaction called dehydration synthesis. | Starch Structure, Function & Chemical Formula, Glycolipids | Function, Structure & Location. When glucose molecules repeatedly undergo dehydration synthesis reactions with other glucose molecules, they form complex carbohydrates like glycogen, amylose starch, or amylopectin starch, depending on how they are put together. At the branch points, subunits are joined by a1g6 glycosidic bonds. Glycogen is an analogue of starch, which is the main form of glucose storage in most plants, but starch has fewer branches and is less compact than glycogen.
