Study Notes
Definition and Classification
- Carbohydrates are biomolecules that serve as energy sources for the body
- Classified into three main categories:
-
Monosaccharides (simple sugars): cannot be broken down further into simpler sugars
- Examples: glucose, fructose, galactose
-
Disaccharides: composed of two monosaccharides bonded together
- Examples: sucrose (glucose + fructose), lactose (glucose + galactose)
-
Polysaccharides: composed of three or more monosaccharides bonded together
- Examples: starch, glycogen, cellulose
-
Monosaccharides (simple sugars): cannot be broken down further into simpler sugars
Functions in the Body
- Primary source of energy for the body
- Broken down into glucose, which is then used by cells for energy production
- Excess carbohydrates can be stored as glycogen in the liver and muscles
- Important for proper brain function and development
Sources of Carbohydrates
-
Plant-based sources:
- Fruits, vegetables, grains, legumes, and nuts
- Examples: bread, rice, pasta, potatoes, corn
-
Animal-based sources:
- Dairy products, such as milk and cheese
- Examples: lactose in milk, glycogen in meat
Importance of Carbohydrates in the Diet
- Provide energy for the body
- Help maintain healthy blood sugar levels
- Important for athletic performance and endurance
- Can help with weight management and satiety
