How does the metabolism of sucrose differ from the metabolism of glucose?

Glucose is the only sugar that the human body can use for production of energy, thus any other sugar that enter the body must first be converted to glucose before it can be metabolized through the glycolytic pathway.

In the body, sucrose will first be broken down into glucose and fructose, the glucose will enter the glycolytic pathway while the fructose will be converted to glycogen and send to the liver.

When glucose is inadequate in the body system, the glycogen in the liver will be converted into glucose and it will enter into the glycolytic pathway.
