Document Summary
Chains of these all joined together polysaccharides when we want to store sugar (enough) for many days store it as glycogen big chains of glucose monomers joined together. G = protein at the core chain of glucose all branching off each other regular structure length of the chain differs 12 14. 5 layers of branched chains cell would go up to 12 layers. Each chain has a branch point going off of it 5 layers here but in reality there is 12, This happens when there is excess glucose around and we want to store it as glycogen. No reducing ends (no anomeric carbon able to reduce all involved in glycosidic linkages) Great if you need glucose quickly enzymes will cut off the glucose one at a time. Starch similar type of linkages but varies in how frequently they are used. Amylose is one big long chain doesn t really branch (very few)
