Details of Each Monosaccharide:
- Glucose:
- Known as blood sugar
- Main source of energy for the body
- Found in carbohydrates like rice, bread, and fruits
- Fructose:
- Found naturally in fruits and honey
- Sweetest natural sugar
- Galactose:
- Usually found as part of lactose (milk sugar)
- Converted into glucose in the liver
Key Features:
- All three have the same chemical formula: C₆H₁₂O₆
- Differ in structure and function
Conclusion:
Glucose, fructose, and galactose are the most important and commonly known monosaccharides, playing a key role in energy metabolism.
