Glycogen can be digested by humans. Chitin and Cellulose, also knows as fiber, can not be digested by humans.
cellulose
Lysosomes pour enzymes into the vacuole to break apart (digest) the chains of glycogen into glucose.
Salivary amylase is not able to digest cellulose. Amylase has the ability to digest starch but cellulose is a fibre which in indigestible.
Cellulose is a type of dietary fiber found in plant cell walls that humans cannot digest. Glycogen is a form of stored glucose in animals, while sucrose and starch are forms of carbohydrates that can be broken down by the body for energy.
Cellulose is a structural polysaccharide found in plants, providing rigidity and support due to its beta-linkages which humans cannot digest. On the other hand, glycogen is an energy storage polysaccharide found in animals, with alpha-linkages for rapid energy release in the body. Cellulose is insoluble in water and forms long, linear chains, while glycogen is more branched and water-soluble.
Glycogen same as the animals kingdom
glycogen cardiomyopathy
glycogen phosphorylase, glycogen debranching enzyme, phosphoglutomutase
Glycogen phosphorylase can not cleave the alpha-1,6-glycosidic bonds at glycogen branch points
Glycogen is the polysaccharide that serves as the main storage form of glucose in the liver and muscles for energy. When energy is needed, glycogen can be broken down to release glucose for use by the body.
glycogen
Liver glycogen has low glycogenin content as compared to muscle glycogen.. liver glycogen responds to glucagon but muscle glycogen responds to catecholamines.. liver glycogen is used for the maintenance of blood glucose levels, but muscle glycogen is used for the supply of energy to the muscles liver glycogen can be completely broken down to glucose because of the presence of glucose 6 phosphatase, which does not occur in the muscles
