1. Simple Sugars (Monosaccharides):
* Basic Building Blocks: These are the simplest forms of sugars. They are single-molecule carbohydrates, like glucose (blood sugar), fructose (found in fruits), and galactose (found in dairy).
* Chemical Formula: They have a general formula of (CH2O)n, where 'n' is a whole number (e.g., glucose is C6H12O6).
* Sweetness: They contribute to the sweetness of food and beverages.
2. Disaccharides:
* Two Simple Sugars: These are formed when two simple sugars join together. Common examples are sucrose (table sugar, glucose + fructose), lactose (milk sugar, glucose + galactose), and maltose (malt sugar, glucose + glucose).
* Digestion: Our bodies break down disaccharides into monosaccharides for absorption.
3. Complex Carbohydrates (Polysaccharides):
* Many Simple Sugars: These are long chains of simple sugars linked together. Examples include starch (from plants), glycogen (stored in the liver and muscles), and cellulose (a structural component of plants).
* Energy Storage: Complex carbohydrates are important for long-term energy storage and structural support in living organisms.
4. Other Uses:
* Food Science: Sugars are used extensively in food production for sweetness, texture, preservation, and fermentation.
* Medicine: Sugars are used in various pharmaceuticals, intravenous solutions, and diagnostic tests.
* Biochemistry: Sugars are essential for cellular metabolism, energy production, and communication between cells.
