4. Carbohydrates Major source of energy for your body Two main forms:
Sugars
Starches

5. Sugars Monosaccharides Disaccharides Glucose, Fructose, Galactose
Maltose, sucrose, lactose

6. Monosaccharides Commonly called “simple sugars”
Glucose – the ONLY ONE that can be immediately used by your body!
Fructose (often found in fruit) – must be further digested and broken down before use.

7. Disaccharides
Must be broken down into monosaccharides before they can be used.
Sucrose (table sugar) – must be broken down further for the body to use as energy.

8. Disaccharides Lactose – sugars found in milk.

9. Starches Polysaccharides
Starches are long chains of sugars that are chemically bonded.
Found in grains, legumes (beans with pods), and root vegetables.
