glucose

Glucose is a type of sugar that is found in foods and drinks. It is the body's main source of energy. Glucose is also used to store energy in the liver and muscles.

When we eat food, our bodies break down the carbohydrates into glucose. Glucose then enters the bloodstream and is carried to the cells. The cells use glucose for energy or store it for later use.

If there is too much glucose in the bloodstream, the body will store it as glycogen in the liver and muscles. If the body needs more energy, it will break down the glycogen back into glucose.
