Definition and Classification

Carbohydrates are biomolecules that serve as energy sources for the body
Classified into three main categories:
1. Monosaccharides (simple sugars): cannot be broken down further into simpler sugars
  - Examples: glucose, fructose, galactose
2. Disaccharides: composed of two monosaccharides bonded together
  - Examples: sucrose (glucose + fructose), lactose (glucose + galactose)
3. Polysaccharides: composed of three or more monosaccharides bonded together
  - Examples: starch, glycogen, cellulose

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
