1. KEY CONCEPT Carbon-based molecules are the foundation of life.

2. Many carbon-based molecules are made of many small subunits bonded together.
Monomers are the individual subunits.
Polymers are made of many monomers.

3. Four main types of carbon-based molecules are found in living things.
#1 = Carbohydrates are made of C, H, O…used for energy in cells….can be mono, di-, or polysaccharides.

4. Many contain carbon chains called fatty acids.
#2 = Lipids are nonpolar molecules that include fats, oils, and cholesterol----made of C, H, O that make up cell membranes and are used for energy
Many contain carbon chains called fatty acids.
Fats and oils contain fatty acids bonded to glycerol.
Triglyceride

5. #3 = Proteins are made of amino acids, are made of C, H, O, N…
#3 = Proteins are made of amino acids, are made of C, H, O, N….are enzymes that run all chemical rxns, are muscle, hair, nails

6. #4 = Nucleic acids are made of C, H, O, N, P
Types: DNA, RNA
DNA stores genetic information.
DNA
RNA builds proteins.
