1. Organic Molecules

2. Macromolecules Macromolecules are “giant molecules” found in living cells Smaller units are called monomers, these join together to form polymers

3. Organic Compounds 4 groups of organic compounds found in living things are: –Carbohydrates, –Lipids, –Nucleic –Acids and Proteins These organic compounds are sometimes referred to as Biomolecules or Carbon Compounds

4. Carbohydrates Living things mainly use carbohydrates as a source of energy. But, they have many other uses as well.

5. Lipids Lipids are used to store energy Lipids are also important parts of biological membranes and waterproof coverings

6. Nucleic Acid Nucleic Acids are molecules containing Hydrogen, Oxygen, Nitrogen, Carbon, and Phosphorous. Nucleic Acids store and transmit hereditary information There are two kinds of Nucleic Acids (RNA and DNA)

7. Proteins Proteins are macromolecules containing Nitrogen as well as Carbon, Hydrogen, and Oxygen Proteins are polymers of molecules called amino acids.
