Common compounds that are examples of disaccharides include sucrose, lactose, maltose, and trehalose.
Explanation:
- Disaccharides are formed when two monosaccharides are linked by a glycosidic bond.
- These compounds are widely found in foods and play a key role in energy supply.
Examples with Composition:
- Sucrose:
- Glucose + Fructose
- Found in table sugar, fruits
- Lactose:
- Glucose + Galactose
- Found in milk and dairy products
- Maltose:
- Glucose + Glucose
- Found in germinating grains and starch digestion
- Trehalose:
- Glucose + Glucose
- Found in mushrooms, yeast, and insects
Key Point:
- All disaccharides follow the general formula C₁₂H₂₂O₁₁
Conclusion:
Sucrose, lactose, maltose, and trehalose are the main compounds classified as disaccharides, each formed from two monosaccharide units.
