A molecule of amylopectin may contain many thousands of glucose units with branch points occurring about every 2530 units. Glycogen has far more 1,6 glycosidic bonds and is therefore far more branched. It has a very simple formation, mainly being made from alpha glucose or, in simple terms, sugar. the liver and skeletal muscle. 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. Glycogen is abundantly present in liver and also For some plants, it is their only means of producing and storing energy. Glycogen is found in animals and functions as a form of stored energy for animals. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. This means it is very branched and so more compact than amylopectin, and it can be broken down very rapidly to provide the glucose fuel needed for cellular respiration. You should know, both of these are complex compounds, and if you do not have a history in biology, it might get tricky for you to understand the difference and everything else.

Although glycogen and starch are both storage molecules, their structures are very different, which is why animals have to break down starch into glucose and then rebuild it as glycogen. Glycogen is more compact than starch, forming glycogen granules in cells. Starch and glycogen are both polymers formed from alpha glucose, produced by repeated condensation reactions between glucose molecules (making amylose and amylopectin).
