Glucose (GLC) is a monosaccharide (or simple sugars) with the chemical formulaC6H12O6. This is the main sugar that circulates in the blood of an animal-freehigh levels, and fuel are favored by the brain and nervous system, as well as red blood cells (erythrocytes).

As the universal substrate (molecule upon which an enzyme acts) for the production of energy cells, glucose is very central role in the metabolism of all life forms. This is one of the main products of photosynthesis, the process by which such fotoautotrof plants and algae convert energy from sunlight intochemical potential energy used by cells. Glucose is also the major starting pointfor cellular respiration, where the chemical bonds of the molecules rich inenergy as glucose is converted into energy that can be used for the process of life.

Glucose is an example of the striking of the complex interrelationship betweenplants and animals: plants capture the Sun's energy into a molecule of glucose,converting to a more complex form (starch or cellulose) are eaten by animals, which restores the original glucose units, send them to their cells, and finallyusing solar energy stored for their own metabolism. Cow's milk, for example,grazing on the grass as a source of cellulose, which they broke into glucose to use their stomach with four chambers. Some glucose which is then entered into the milk we drink.

Glucose is essential for the human body and to the brain, it is important to maintain blood glucose levels is rather constant. For those with diabetes mellitus, a disease in which levels of glucose in the blood is too high, thepersonal responsibility (i.e. self management) is the key to treatment. For diabetes there is usually a complex treatment program involving a special diet, exercise, medications, stress management, and other elements (the UWMedicine 2006).

All carbohydrates are the main foods that contain glucose, either as just onebuilding block them, or in combination with another monosaccharide, as insucrose (table sugar) and lactose, the main sugar found in milk.

The natural form of glucose (D-glucose) is also referred to as dekstrosa, especially in the food industry.

When oxidized in the body in a process called glucose metabolism, producescarbon dioxide, water, and nitrogen compounds and in the process provide the energy that can be used by cells to produce energy. approximately 686kilokalori (2870 kilojoules) per mole that can be used to do work or help keep the body warm. This Energy is the number of changes Gibbs free energy ΔG orin reaction to, the size of the maximum amount of work can be obtained fromthe reaction. As the main source of energy in the body, does not requiredigestion and often provided intravenously to people in hospital as nutrients.

Energy from glucose is obtained from the oxidation reactions

C6h12o6 + 6O2 6CO2 + 6H2O > –

where one mole of glucose (approx. 180 grams) reacts with six mol O2 withproduce energy ΔG = 2870 kJ. The six moles of oxygen at STP will occupy 6 x 22.4 L = 134 liters. Produce energy from glucose is often stated as a result per liter of oxygen, which would be 5.1 kcal per litre or 21.4 kJ per liter. Energy produced can be measured by completely burning glucose and measuring theenergy released in the kalorimeter.

But in living organisms, glucose oxidation contribute to a complex series ofbiochemical reactions that provide the energy needed by cells. The first step inthe breakdown of glucose in all the cells is Glycolysis produce pyruvate, which is the starting point for all other processes in cellular respiration. In the cells whereoxygen is present (aerobic respiration) this process has been modelled in theTCA or Krebs cycle. Most of the use of energy from the oxidation of glucose is the conversion of ADP into ATP, the energy rich ATP molecules are further used as energy currency of the cell.

Glucose is produced by the plant with the help of energy from the Sun in a process called photosynthesis. The synthesis is done in the little energy factoriescalled chloroplasts in leaves of plants. Chloroplasts capture light energy fromglucose molecules and made of carbon dioxide from the air and water from the soil.
