Building Blocks

2 ALL must contain Carbon, Hydrogen and Oxygen.
Organic Molecules ALL must contain Carbon, Hydrogen and Oxygen.

3 Monomer Single Unit

4 Single units bonded together
Polymer Single units bonded together

5 Sugars Energy Structure
Carbohydrates Sugars Energy Structure

6 Carbohydrates – “saccharide”
Monomer = Monosaccharides Glucose Fructose

7 Carbohydrates = sugars
Polysaccharides Cellulose Chitin Starch Test: Benedict’s Solution
