No, water is not typically removed to make glycogen. Glycogen is a complex carbohydrate made by the body from glucose and stored in the liver and muscles for energy. It is synthesized through glycogenesis by linking glucose molecules together in a process that does not involve removing water.
When glucose is polymerized to form glycogen or starch, a water molecule is removed during each condensation reaction between glucose molecules. This process is known as dehydration synthesis.
Glucose is removed from the blood mainly through insulin-mediated processes. Insulin facilitates glucose uptake by cells for energy production, storage, or conversion into glycogen or fat. Additionally, glucose may also be removed from the blood via processes like hepatic glucose output or uptake by tissues such as the brain.
When joining individual glucose monomers together to form a polysaccharide like starch or glycogen, a water molecule is removed in a condensation reaction to form a glycosidic bond.
Glucose can be removed from the bloodstream by cells through the process of cellular respiration, where glucose is broken down to produce energy. It can also be taken up by the liver and converted to glycogen for storage. Additionally, insulin helps facilitate the uptake of glucose by cells, lowering its concentration in the bloodstream.
GlucagonINSULIN causes glucose to be removed from the blood stream by having it stored in the form of Glycogen in muscle and liver cellsGLUCAGON causes glycogen to be broken down from liver and muscle tissue and releases glucose into the blood stream, thus increasing circulating blood glucose levels. The hormone, released by the pancreas, is insulin.
Fifteen molecules of glucose can be used to form polysaccharides, specifically starch or glycogen, through a process called polymerization. In this process, the individual glucose molecules undergo dehydration synthesis, where water is removed to link them together. The resulting macromolecule will consist of a long chain of glucose units, serving as an energy storage form in plants (starch) or animals (glycogen).
The pancreas essentially produces two hormones for blood glucose control. These are glucagon in response to low blood glucose levels and insulin in response to high blood glucose levels. The pancreas produces glucagon in response to low blood glucose levels. It is a linear polypeptide produced by the acini cells of the islets of langerhans. This hormone allows glycogenolysis and gluconeogenesis to take place in the liver first and then muscle tissue. Glycogenolysis is the breakdown of glycogen to glucose which is then released into blood plasma to increase blood glucose levels. This occurs in the liver until glycogen stores in the liver are depleted and muscle glycogen stores are used. Gluconeogenesis is the synthesis of amino acids to form glucose which is then released into blood plasma to increase blood glucose levels. It also stimulates lypolysis which is the break down of fats. The pancreas produces insulin in response to high blood glucose levels. It is also a polypeptide but is produced by the beta cells of the islets of langerhans. It increases cellular uptake of glucose which is removed from the blood, thus lowering blood glucose levels. This happens in most cells except the brain. It also fosters glycogen storage in the muscle and liver and promotes lipogenesis mainly in adipose tissue and the liver. It has one last effect. That is to stimulate protein synthesis from amino acids entering cells and inhibit protein degradation, effecting growth.

In order to join multiple glucose molecules together to form larger polysaccharides like starch or glycogen, water molecules must be removed in a condensation reaction. This process involves the removal of a hydroxyl group (-OH) from one glucose molecule and a hydrogen atom (-H) from the other glucose molecule, resulting in the formation of a glycosidic bond between the two glucose units. This dehydration synthesis reaction requires energy input to proceed and results in the release of a water molecule as a byproduct.
