What two things happen to sugars when they pass into the blood stream?

1. They are converted to glucose. Glucose is the body's main source of energy, and it is the only type of sugar that can be used by the brain.

2. They are stored as glycogen. Glycogen is a complex carbohydrate that is made up of glucose molecules. It is stored in the liver and muscles, and it can be broken down into glucose when the body needs energy.
