Transcribed image text: In … WebGlycogen is a molecular polymer of glucose (a polysaccharide) used to store energy, and is important for maintaining glucose homeostasis in the blood, as well as for providing energy for skeletal muscle and cardiac muscle contraction. Molecules of glucose are linked into linear chains by α-1,4-glycosidic bonds.Additionally, branches of glucose are formed off …
WebIn glycogen, glucose molecules are attached one after the other by alpha-1,4 linkages. However, in order to make glycogen more compact for storage, branch points are created to created links between many shorter glucose polysaccharides. These branch points connect glucose molecules by alpha-1,6 linkages.
