If no glucose is available from dietary carbohydrate, glucose in the blood may be derived from glycogen.
Glycogen is a biomolecule that is part of carbohydrates.
It is a polysaccharide, since it is made up of a chain of ten or more monosaccharides, it is one of the energy storage molecules most used by living beings.
There are two types of glycogen:
- Hepatic glycogen, which is responsible for regulating the concentration of glucose in the blood.
- Muscle glycogen, which is the one whose mission is to maintain and meet the needs of the muscles during the development of any sporting activity.
When an individual requires an emergency energy dose, for example if he is in a state of alert or in a moment of tension, the body rapidly breaks down glycogen and transforms it into glucose, incorporating it into the metabolism.
Therefore, we can conclude that glycogen is stored by the body as a reserve until, when it is time for its use, it is converted into glucose (a monosaccharide).
