What is the chemical formula of glucose?
1Answer
The chemical formula of glucose is C₆H₁₂O₆.
Glucose is a simple sugar (monosaccharide) and the primary source of energy for living organisms. It exists in two cyclic forms (α-glucose and β-glucose) in solution, but its open-chain form is represented by the empirical formula C₆H₁₂O₆.
Structurally, glucose is a hexose sugar with six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. Its molecular structure can be written as:
CH₂OH
|
CHOH
|
CHOH

CHOH

CHOH

CO
This linear structure cyclizes to form a six-membered ring (pyranose form) in aqueous solutions. The most common form of glucose in biological systems is D-glucose.
