The molecular formula of sucrose is:
Correct answer: A. C12H22O11
- A. C12H22O11
- B. C6H12O6
- C. C3H6O3
- D. C5H10O5
Explanation
Sucrose is a disaccharide formed by the condensation of glucose and fructose monomers, resulting in the removal of a water molecule (H2O). This process forms a 1,2-glycosidic bond, leading to the molecular formula C12H22O11, making Option A correct. Options B, C, and D represent different compounds: glucose, glycerol, and an undefined carbohydrate structure, respectively. They do not correspond to the molecular composition of sucrose.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
