Glucose – Definition, Facts, and Formula

Glucose is something that every living thing requires to perform her/his daily life activity. Also, it tastes sweet in taste. Besides, the glucose formula is a chain of hydrocarbons.

glucose formula


Glucose comes from the Greek word ‘glukus’ which means ‘sweet’. Also, it is a monosaccharide that is another term for simple sugar. Besides, it is among the three monosaccharides that the body uses. But, it is the only one that directly used to produce ATP (Adenosine Triphosphate).

Also, the body uses ATP to produce energy: in fact, it is the only molecule in the body that we can use for energy and that’s why an adequate level of glucose level is essential. Besides, glucose is both useful and harmful to the organisms.

Most noteworthy, Glucose is used by the cells to make ATP that power the body. However, Hyperglycemia (High blood sugar or glucose) is a cell-killing (cytotoxic) and can induce severe inflammation throughout the body.

In addition, Hypoglycemia (low blood sugar or glucose) is a condition in which the sugar level is quite low than average and this too is harmful and deadly. Besides, the body has many ways to detect glucose levels in the body and mechanism to correct them. Moreover, when the body is not able to regulate blood glucose level diseases such as diabetes occur.

Facts about Glucose

The ‘ose’ ending of glucose indicates that it is a carbohydrate molecule. Also, due to the presence of six molecule scientists classify it as a hexose. If we talk specifically then it is an aldohexose. Furthermore, it can be found in the cyclic form (common) and linear form.

Moreover, the –OH group is able to move freely around the carbon atom in glucose that leads to isomerization. In addition, the D-glucose and D-isomer, originate in nature and plants and animals use them for cellular respiration. Besides, the scientists prepare the L-glucose and L-isomer in the lab and they do not originate in nature.

Also, pure glucose is a crystalline or white powder that has a molar mass of 180.16 grams per mole and has a density of 1.54 grams per cubic centimeter. Besides, the melting point of it depends on its beta conformation. Moreover, the melting point of α-D-Glucose is 146 degrees Celsius and the melting point of β-D-glucose is 150 degrees Celsius.

Furthermore, glucose is less likely to react with amine groups of proteins. Besides, the reaction between the proteins and carbohydrates is termed as glycation and it is a natural part of aging and consequences of some diseases that harms the working of proteins.

On the contrary, glucose can be enzymatically added to lipids and proteins through the process of glycosylation that forms active glycoproteins and glycolipids. Inside the human body glucose supply about 3.75 kilocalories of energy per gram.

Also, the body metabolizes it into carbon dioxide and water, producing energy in the chemical form as ATP. Moreover, glucose is necessary because it supplies nearly all the energy for the human brain.

Glucose Formula

Glucose formula at the molecular level is C6H12O6 or H-(C=O)-(CHOH)5-H. Besides, its simplest formula is CH2O that indicates there are two hydrogen atoms for each carbon and oxygen atom of the molecule.

Moreover, glucose is a sugar that plants produce during photosynthesis and circulates in the blood of other animals as a source of energy. Also, it is known as dextrose, blood sugar, grape sugar, and corn sugar.

Solved Question on Glucose Formula
