1. KEY CONCEPT: Carbohydrates are important because they are the body’s main energy source. Carbohydrates

2. Composed of carbon, hydrogen, & oxygen “Think CHO” -Ratio of 1:2:1 Monomer  Monosaccharides  (Simple sugar)  Most common-  GLUCOSE Carbohydrates

3. Disaccharides – double sugars ▫ Example - sucrose Carbohydrates

4. Polysaccharides – many sugars ▫ Examples – starch, cellulose, chitin Carbohydrates

5. They are the main source for the body to gain energy. They are our fuel! They make up the cell wall in plants which allow them to grow tall, without this carbohydrate, a plant would be a mushy mess! This type of carbohydrate is called Cellulose. THINK: CARBS= ENERGY and CELL WALLS What do carbs do?

6. Two types: Simple Complex Simple Sugars are carbohydrates made up of 1 or 2 monomers. They also taste sweet. Monosaccharide = 1 sugar Disaccharide = 2 sugars Complex Cabohydrates are polymers made up of many monomers. Most also taste starchy. Polysaccharide = many sugars

7. Simple Sugars

8. Complex Carbohydrates
