1. The Chemicals of Life
Organic Chemistry

2. Organic?
What does it mean when a food or another product is given the label ORGANIC?

3. Organic?
Containing carbon compounds found in living organisms or produced by living things.

4. The Chemicals of Life
There are 4 chemicals that are important for Life. They are:
Carbohydrates
Proteins
Lipids (Fats)
Nucleic Acids (DNA & RNA)

5. What is the purpose of carbohydrates within living things?

6. CARBOHYDRATES
Purpose: plants produce carbos, to supply the basic food energy for all living things.
Building Blocks: Monosaccharide or single sugars (ex. Glucose)
Macromolecules: Polysaccharides
Ex. starches, cellulose (fiber), glycogen.

11. What is the purpose proteins in living organisms?

12. PROTEINS
Purpose: Structure of living things; growth, maintenance, & repair; & run chemical reactions of the organism.
Building Blocks: Amino Acids; 20 different AA found in living things make the thousand different proteins of living things.
A protein is made of a chain of amino acids held together by peptide bonds.
Macromolecules: Polypeptide
enzymes & structural proteins

14. LIPIDS (FATS)?
What is the function of fats within living things?

15. LIPIDS (FATS)
Purpose: Energy storage; cell membranes; chemical reactions, insulation (ex. Hormones, pigments)
Building Blocks: Fatty Acids & Glycerol
Macromolecules: Fats, Waxes & Oils, Steroids & Cholesterol

21. NUCLEIC ACIDS Purpose: Carry the Hereditary materials of Life.
Building Blocks: nucleotides
Macromolecules: DNA & RNA
