Many speculated that this could mean Damien Wayne, son of the Dark Knight, who has connections to Ra's, but that seemed unlikely (edit: ironically, it's come to my attention the Facebook page for Moviepilot actually shared this as Damien Wayne. That's an error such as the one above).
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals and fungi. The polysaccharide structure represents the main storage form of glucose in the body.In humans, glycogen is made and stored primarily in the cells of the liver and the muscles hydrated with three or four parts of water.uscle glycogen is converted into glucose by muscle cells, and liver glycogen converts to glucose for use throughout the body including the central nervous system.
The body breaks down most carbohydrates from the foods we eat and converts them to a type of sugar called glucose. Glucose is the main source of fuel for our cells. When the body doesn't need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen. When the body needs a quick boost of energy or when the body isn't getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells.
