Gylcogen

• Glycogen is found in animals and bacteria.
• Glycogen is never found in plants.
• Glycogen is very similar in strucuture to starch but has shorter chains and is more highly branched.
• Glycogen is the major carbohydrate storage product of animals.
• In animals glycogen is mainly stored in small granules in the muscles anf the liver.
• Glycogens function is storage.
• Glycogen is adapted by: it is insoluble and therefore soen't tend to draw water into the cells by osmosis.
• Glycogen is adapted by: being insoluble, it dosen't diffuse out of cells
• Glycogen is adapted by: it is compact, so a lot can be stored in a small space.
• Glycogen is made up of alpha-glucose
• Glycogen is adapted by: it is more highly branched so has more ends that can be acted upon simulaneously by enzymes.
