The molecular mass of glucose molecule (C6H12O6) is 180 u.

Step1. Molecular Mass

  • The most recent IUPAC proposal states that one carbon atom has a mass equal to one atomic mass unit (formerly abbreviated as “amu,” but now written “u” – unified mass).
  • Atomic mass, measured in amu, is added to determine molecular mass.

Step2. Formula for the glucose (C6H12O6) molecule’s molecular weight

We know that the molecular mass of C6H12O6=6×The atomic mass of C + 12 × The atomic mass of H + 6 × Atomic mass of O

Step3. Now we have to calculate of molecular mass of glucose molecule

The molecular mass of glucose(C6H12O6)= 6×12.01+12×1.0079+6×16u


On simplifying we get




It is also known as dextrose. Since it contains an aldehyde group and six carbon atoms, it is known as aldohexose. It comes in two varieties: ring structure and open-chain. It is created by the kidneys and liver of animals. It can exist in plants and be found in their fruits and other parts. D-glucose is the kind of glucose that occurs naturally. It might manifest as a liquid or a solid. It is soluble in both acetic acid and water. It tastes wonderful and has no fragrance. In the year 1747, German chemist Andreas Marggraf made the discovery that raisins contain glucose. The term glucose was first used in 1838 by Jean Baptiste Dumas.

Uses of Glucose

  • It is utilised to treat hypoglycemia (low blood sugar)
  • It is given to people who are very ill and unable to eat since it contains energy from carbohydrates.
  • It is applied to the management of elevated blood potassium levels (hyperkalemia)
  • It serves as a starting point for the synthesis of many compounds.
