The Formula of Glucose and Sucrose: Understanding Sugar's Molecular Composition

Sugar, a common ingredient in our daily lives, is scientifically known as sucrose. It is a disaccharide composed of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. The chemical formula of table sugar or sucrose is C12H22O11. This intricate molecular structure is formed by the combination of two simpler sugars, glucose and fructose, each with its own unique chemical formula.

The Chemical Formula of Glucose and Sucrose

Glucose, a fundamental monosaccharide, is among the simplest and most abundant sugars. Its chemical formula is C6H12O6. Glucose is a hexose, meaning it has six carbon atoms in its ring structure. Just as sucrose, fructose, another common hexose, also has the chemical formula C6H12O6.

Forming Sucrose from Glucose and Fructose

The formation of sucrose from glucose and fructose involves a simple yet fascinating chemical process. When these two hexoses are combined, a water molecule is removed, leading to the formation of a disaccharide compound. This process is known as dehydration synthesis.

The Chemical Reaction

The chemical equation for the formation of sucrose from glucose and fructose is as follows:

Glucose Fructose - Sucrose Water

Explanation

Both glucose and fructose are hexoses, each having the same molecular formula C6H12O6. When they react together, the molecules rearrange themselves to form sucrose (C12H22O11) and release a water molecule in the process. The chemical name for sucrose is alpha-d-glucopyranosyl-beta-d-fructofuranoside, which accurately describes its molecular structure and the specific arrangement of its sugar components.
