1. Monosaccharides (Simple Sugars)
* Structure: Single sugar units.
* Examples: Glucose, fructose, galactose.
* Uses:
* Glucose: The primary energy source for the body's cells.
* Fructose: Found naturally in fruits and honey; provides sweetness.
* Galactose: Part of lactose (milk sugar).
2. Disaccharides (Double Sugars)
* Structure: Two monosaccharides linked together.
* Examples: Sucrose, lactose, maltose.
* Uses:
* Sucrose (table sugar): Provides sweetness, but excess consumption can lead to health issues.
* Lactose (milk sugar): Important for infant nutrition; some individuals are lactose intolerant.
* Maltose: Found in germinating grains; provides sweetness.
3. Polysaccharides (Complex Carbohydrates)
* Structure: Many monosaccharides linked together in long chains.
* Examples: Starch, glycogen, fiber.
* Uses:
* Starch: Found in plants, a primary source of energy.
* Glycogen: Stored form of glucose in the liver and muscles.
* Fiber: Indigestible by humans but important for digestive health and regulating blood sugar levels.
Additional Notes:
* Dietary Fiber: While technically a polysaccharide, fiber is not broken down by the body for energy and plays a crucial role in maintaining a healthy digestive system.
* Carbohydrates are essential for providing energy to the body. However, it's important to consume a variety of carbohydrate sources and prioritize complex carbohydrates over simple sugars.
