However, glycogen consists of only one component whose structure is similar to amylopectin. The protein glycogenin, which is involved in glycogen synthesis, is located at the core of each glycogen granule. Although glycogen and starch are both storage molecules, their structures are very different, which is why animals can only store complex carbohydrates as glycogen, but not starch, which is specific to plants. Glycogen is the storage molecule in animals, starch in plants. Which is FALSE about cellulose? Glycogen occurs in the form of small granules. Both these polysaccharides are good energy sources for humans and animals. Glycogen shapes a vitality hold that can be immediately assembled to meet an unexpected requirement for glucose, yet one that is less reduced than the vitality stores of triglycerides (lipids). With cellulose, it is the beta molecules that link together. The granules swell and burst, the semi-glasslike structure is lost and the littler amylose atoms begin draining out of the granule, framing a system that holds water and expanding the blends thickness. Glycogen has a molecular weight greater than 3 million. In plants, starches are produced in plastids. Glycogen is the analogue of starch, a glucose polymer that functions as energy storage in plants.
