How does the body get glucose?
Glucose is a type of sugar that the body derives or synthesizes from food during metabolism. The body draws glucose from carbohydrates most readily, although it can also convert proteins and fats into glucose. Carbohydrates include monosaccharides, or simple sugars, like fructose and galactose; disaccharides, which are combinations of fuctose, galactose and glucose; starches; and cellulose, or fiber, although fiber is indigestible and thus does not provide energy. The body derives glucose fastest from fructose, typically within 15 minutes, according to Sarí Harrar and Julia VanTine in "Prevention's the Sugar Solution." However, it can take up to eight hours to absorb glucose from fat or protein.

Does sucrose raise energy?
Consuming sucrose and other types of sugar appear to raise energy levels in proportion to the amount consumed. In fact, consuming sugar in large enough amounts can result in a burst of energy known as a sugar high that ends in a sharp drop in energy levels, termed a "crash.".

How to store glucose in the body?
Glucose can also be stored in the liver and muscles as glycogen. Glycogen then acts as an energy reserve that's used when your blood glucose levels drop, such as when you exercise. You need to consume carbohydrates to keep your glycogen replenished. Eating fruits, vegetables, dairy and whole grains will help you keep an adequate store of glycogen so your glucose levels remain steady when you're exercising, according to an article from Iowa State University. Most adults can store enough glycogen to replace glucose during 90 minutes of low-intensity exercise or up to 20 minutes of vigorous exercise. These backup stores are crucial to keeping your blood sugar stable.
