[ Glucose, D-glucose, Dextrose ]

A monosaccharide with the molecular formula C6H12O6. The principle isomer of glucose is D-glucose (dextrose). It is the product of photosynthesis and the building block of a number of important carbohydrate polymers, including cellulose.

In animals, glucose is the defining sugar of the blood. It is obtained from directly from dietary glucose, and from the hydrolysis of more complex dietary carbohydrates. Other monosaccharides are converted into glucose, mostly by the liver, making glucose the only source of carbohydrate energy in the body.

Glucose is transported via the blood stream to the mitochondria, where it is converted to ATP via the Krebs Cycle.
