What is the general formula of a disaccharide?

The general formula of a disaccharide is C₁₂H₂₂O₁₁.

Explanation:

• Disaccharides are formed by the combination of two monosaccharide molecules.
• During this process, a molecule of water (H₂O) is removed in a condensation reaction.

Formation Concept:

• Monosaccharide formula: C₆H₁₂O₆
• Two monosaccharides combine:
  C₆H₁₂O₆ + C₆H₁₂O₆ → C₁₂H₂₂O₁₁ + H₂O

Examples Following This Formula:

• Sucrose
• Lactose
• Maltose

Important Note:

• This formula applies to most common disaccharides but may vary slightly in modified structures

Conclusion:
The general chemical formula of a disaccharide is C₁₂H₂₂O₁₁, formed by the combination of two monosaccharides with the loss of one water molecule.
