1. ORGANIC MOLECULES

2. Proteins

3. PROTEIN ELEMENTS: C H O N (sometimes P and S)
BUILDING BLOCKS (SUBUNITS): amino acids (there are 20 amino acids)
FUNCTIONS:
growth and repair
*enzymes – speed reactions (End in –ASE)
Hormones –insulin, controls blood sugar
Immune System – antibodies and white blood cells
Hemoglobin – carries oxygen in the blood
nails, hair, muscle
last resort source of energy*
SOURCES: dairy products, peanuts, meat, fish

4. BONDING OF AMINO ACIDS Amino acids bond together making proteins.
C—N peptide bond forms between amino acids
Amino acids end in: ine or -ate

5. Enzyme - a protein created by an organism that increases the rate at which chemical reactions occur.

6. Nucleic acids

7. NUCLEIC ACIDS ELEMENTS: C H O N P BUILDING BLOCKS: nucleotides
Sugar + phosphate + N base
FUNCTIONS: 1. genetic blueprints
2. transferring information
EXAMPLES: DNA and RNA
