What type of glycosidic linkages are developed when excess glucose is to be stored for future use in animals?

In animals, excess glucose is stored as glycogen, a polysaccharide that serves as a form of energy reserve. Glycogen is made up of glucose molecules connected by glycosidic linkages, and it has a highly branched structure.
- Alpha-1,4 glycosidic linkages connect glucose units in the linear chain of glycogen. These linkages form between the hydroxyl group on carbon 1 of one glucose molecule and the hydroxyl group on carbon 4 of the next glucose molecule.
- Alpha-1,6 glycosidic linkages occur at the branch points of the glycogen molecule. These linkages form between the hydroxyl group on carbon 1 of one glucose molecule and the hydroxyl group on carbon 6 of another glucose molecule, creating the branches.
