Glucose; (also known as Dextrose, D-Glucose or Grape Sugar) is a Monosaccharide sugar found in plants. Also, Glucose is the primary product of a plants process of photosynthesis.

The name "Glucose" comes from the Greek word “glukus” meaning "sweet". Emil Fischer won a Nobel Prize in 1902 for his work in biochemistry including his investigations into Glucose.


Glucose can be manufactured from Starch by the addition of enzymes or in the presence of acids. Glucose Syrup is a liquid form of Glucose used by food manufactures.


Glucose, along with Fructose and Galactose, is one of the three dietary simple sugars that is absorbed directly into the blood stream during digestion. In fact, all the Carbohydrates that we eat are broken down into Sugars (Monosaccharides and Disaccharides) and converted into Glucose through digestion.

Glucose is a ubiquitous fuel in biology. It is used as an energy source in most organisms, from bacteria to humans, transported around the bodies of animals in the bloodstream. For example in our human bodies, Glucose is the main sugar fuel source and provides about 3.75 kilocalories (16 kilojoules) of food energy for every .035 ounces (1 gram) .

Glucose is also a primary source of energy for the brain and its availability influences psychological processes. When Glucose is low, mental processes requiring thoughtful effort can be impaired. When there is too much Glucose in the blood excitement and energy can be raised. The insulin reaction and other mechanisms, regulate the concentration of Glucose in the blood.

The intestinal tract metabolizes Glucose in your body, which in turn elevates blood sugar levels. To normalize blood sugar levels your pancreas releases Insulin, a storage hormone. The insulin directs the Glucose to the cells that need extra energy. Any leftover Glucose is stored as Fat.

Continually elevated Glucose levels (Hyperglycemia) can lead to health problems. The pancreas can handle an increased work load, for a while but then it becomes exhausted and its ability to produce insulin deteriorates and blood Glucose levels can rise. Also if insulin release is suffering, Glucose is not being delivered to the cells that need it and some cell starvation occurs.

Over time, Hyperglycemia has been related to: decreased immunity, poor wound healing, nerve damage, kidney failure, high levels of blood lipids, heart attacks, strokes, and obesity.
