1. Inorganic Compounds Inorganic Compounds Do not contain carbon
Water is the most abundant and important inorganic material, making up 60% - 80% of all cells and 2/3 of body weight
Identify the important facts regarding inorganic molecules.

2. Organic Compounds Contain the element carbon
And other elements such as: hydrogen, oxygen, phosphorus, nitrogen, or sulfur
Carbon is found in things that are or once were living.
Have students differentiate between organic and inorganic compounds.

3. Organic Compounds
Organic compounds are composed of hundreds to thousands of individual molecules.
The single molecules in a polymer are called monomers.
The images at the bottom are examples of monomers. Explain to the students that fructose is a simple sugar. The string of beads are also an example of monomers. As the beads are all the same in the string.

4. Organic Compounds
The long molecules formed by repeating patterns of monomers are called polymers.
Compare the structure of the monomers to the polymers. Use the InterWrite tablet to identify the bonds for students.

5. Types of Organic Compounds
4 Types of Organic Compounds carbohydrates, lipids, proteins, and nucleic acids.
Essential to maintaining life processes: cell function, storage, energy, homeostasis and genetic information.
Students are to list all of the reasons why macromolecules are essential to life on their Cornell note sheet. Please allow time for this.

6. Carbohydrates Make up sugars and starches
Contain atoms of carbon, hydrogen, and oxygen.
Provide energy to the cells.
Emphasize the importance of carbohydrates to living things.

7. Lipids The three types of lipids are fats, oils, and waxes.
Contain carbon, hydrogen, and oxygen
Lipids store energy for later use by the body.
Lipids also serve as padding and protection for the body.
Emphasize the three types of lipids. Click link for glycerol and fatty acids to show a diagram of the two structures. Use InterWrite tablets to circle the functional group.

8. Saturated & Unsaturated Fats
Explain the structure.

9. Proteins Proteins are the building materials for the body.
Hair, skin, muscles, and organs are made mostly of proteins.
Composed of carbon, hydrogen, nitrogen, and oxygen
The building blocks of proteins are amino acids (monomers).
Serve as enzymes which control rate of reactions and regulate cell processes.
Identify the functions of proteins.
