Fructose

This is naturally found in fruit, honey, and a few vegetables, particularly cabbage, green beans, and asparagus.

Glucose

This is the most important monosaccharide in the human body because it is a primary fuel for muscle and other cells. Under normal conditions, red blood cells as well as brain and other nervous system cells burn mostly this for energy.
