Glucose Chemical Formula

What Is The Chemical Formula For Glucose: Carbohydrates are the nutritional category of sugars, molecules that our bodies break down into simple sugars. Depending on the complexity of their structure, carbohydrates are divided into simple and complex sugars. Glucose is a simple carbohydrate that serves as an important energy source for living organisms.

What Is The Chemical Formula For Glucose is an important question which should be understood by the learners. A glucose molecule consists of six carbon atoms and one aldehyde group. It is a monosaccharide with the chemical formula C6H12O6. Glucose is the most important carbohydrate for plants and animals, as it is used by cells as an energy source for photosynthesis and respiration. It also serves as a major fuel source for the brain. The glucose molecule exists in her two isomers, D-glucose and L-glucose. What Is The Chemical Formula For Glucose and other important questions can be seen on Extramarks.

Glucose is found in carbohydrate-rich foods such as fruit, honey, and sugar. It is the major source of free sugars circulating in the bloodstream of higher animals. This article details the structure, properties, and uses of glucose. The term “glucose” comes from the Greek word “glykys” which means “sweet”. They are simple sugars, and the chemical formula for glucose is C6H12O6. It is also called “aldohexose” because it contains 6 carbon atoms and an aldehyde group. Glucose molecules can exist in two forms: open chain (acyclic) and cyclic (cyclic). Cyclization of the glucose molecule is the result of an intramolecular reaction between the aldehyde carbon atom and the C-5 hydroxyl group, forming a hemiacetal. Both cyclic and acyclic forms exist in equilibrium, with cyclic being predominant at pH 7. Glucose is also known as glucopyranose because the ring contains five carbon atoms and one oxygen atom. It resembles pyran in structure. In its cyclic form, each carbon is attached to a pendant hydroxyl group and the 5th carbon atom is attached to the 6th carbon atom outside the ring to form a CH2OH group. The answer to What Is The Chemical Formula For Glucose can be found by students on the Extramarks platform.

Characters Suggest The Structure Of Glucose

What Is The Chemical Formula For Glucose and other such questions must be solved by the learners in order to achieve good scores

  1. The formation of n-hexane upon prolonged heating of HI with glucose indicates that all six carbons are in linear chains.
  1. The presence of carbonyl groups in glucose was evidenced by the formation of oximes when glucose reacted with hydroxylamine and cyanohydrin by addition of hydrogen cyanide.
  1. Oxidation of glucose to a carboxylic acid containing six carbon atoms by a mild oxidizing agent such as bromine water indicates that the carbonyl group is in the form of an aldehyde group. 
  1. Acetylation of glucose with acetic acid yields glucose pentaacetate. This confirms the presence of the -OH group. 
  1. The presence of primary alcohols in glucose is indicated by the formation of dicarboxylic and sugar acids by oxidation with nitric acid. isomers of glucose

Reaction Due To Alcoholic (OH) Groups:

What Is The Chemical Formula For Glucose is an important topic students should focus on.

A glucose molecule has four secondary alcohol groups and one primary alcohol group. 

Upon acetylation with acetyl chloride or acetic anhydride, glucose forms the pentaacetyl derivative. This indicates that 5 OH groups are attached to 5 different carbon atoms.



What Is The Chemical Formula For Glucose and its reactions are important topics for Chemistry.

Glucose is reduced by HI, and red phosphorus produces n-hexane upon prolonged heating. This suggests that all six carbon atoms of glucose are connected in a straight chain.




Using a mild oxidizing agent such as bromine water, glucose is oxidized to gluconic acid, a six-carbon monocarboxylic acid. This indicates that the carbonyl group present in glucose is an aldehyde group.What Is The Chemical Formula For Glucose can be accessed easily on Extramarks.


 glucose gluconate

 When oxidized with strong oxidizing agents such as concentrated nitric acid, glucose is oxidized to dicarboxylic acids. Formation of a dicarboxylic acid indicates the presence of a primary alcohol group. Of these, we can conclude that one is of the primary alcohol group and the remaining four are of the secondary alcohol group.

Properties Of Glucose

What Is The Chemical Formula For Glucose must be checked in order to score well in the exams as questions are asked from this topic frequently.

  1. Photosynthesis – Plants produce food glucose in the presence of carbon dioxide, water, and sunlight. It is the main source of energy for plants and oxygen in the environment. The chemical reactions involved in photosynthesis are:


  1. Glycogenolysis – In animals, glycogen, the major carbohydrate stored in animal liver and muscle cells, is broken down into simple glucose molecules to provide immediate energy and maintain blood sugar levels during fasting. What Is The Chemical Formula For Glucose is easily available on the website of Extramarks.

Uses Of Glucose

  1. Glucose is an important factor in maintaining energy levels in the body. Cells in our body need a certain amount of glucose to function properly and red blood cells convert glucose into energy. Neurons in the brain require a continuous supply of glucose to carry out various processes such as thinking, memory and learning. Therefore, the brain requires the greatest amount of glucose of all organs in the body. 
  1. Hypoglycemia (hypoglycemia) is experienced primarily by diabetics. Glucose helps restore normal blood sugar levels. 
  2. Glucose is a fast-acting energy source. Therefore, athletes consume glucose during strenuous physical activity to avoid fatigue. 
  3. Glucose is used as the first-line treatment for “hyperkalemia,” which causes elevated potassium levels in the body.Refer to Extramarks for What Is The Chemical Formula For Glucose.
