1. 2-3 Carbon Compounds p45
Q: What elements does carbon bond with to make up life’s molecules? A:Carbon can bond with many elements, including hydrogen, oxygen, phosphorus, sulfur, and nitrogen to form the molecules of life.

2. The Chemistry of Carbon-basic element of life.

3. Macromolecules
Q: What are the four main groups of macromolecules? A: Carbohydrates, lipids, nucleic acids & proteins. Q: What are the functions of each of the four groups of macromolecules? Q: What is the structure of each of the four groups of macromolecules?

4. Macromolecules Monomers-small units
Polymers-large compound formed from several monomers

5. Carbohydrates
Function- main source of energy living things. Plants, some animals, and other organisms also use carbohydrates for structural purposes.
Monosaccharides-single sugars
Polysaccharides-large macromolecules formed from monosaccharides
Ex: Starch, pasta
Structure: C, H, O

6. Lipids
Function-store energy, biological membrane, waterproof covering.
Saturated-max. # of hydrogen atoms, no double bonds & solid at room temperature.
Unsaturated-less H atoms, double bonds, liquid room temp.
Ex: fats, oils, waxes
Structure: C, H

7. Nucleic Acids Function-Store & transmit genetic info.
Nucleotide-part of the nucleic acid
Ex: DNA & RNA
Structure: C, H, O, N, P

8. Proteins Function- Control the rate of reactions.
Regulate cell processes
Form important cell structures
Transport substances.
Structure: C, H, O, N

9. Amino acids- part of a protein that contains an amino group a carboxyl group.
