Ch. 3.3Organic Compounds
Organic Chemistry
All chemicals can be classified two ways:
1.Organic – Contain Carbon
2.Inorganic – Do Not Contain Carbon
Macromolecules…
“giant molecules”Macromolecules are made from hundreds
or thousands of smaller moleculesThe small units are called monomersA bunch of monomers put together is
called a polymer
Macromolecules
Each macromolecule is made up of smaller parts call monomers.
4 Organic Macromolecules…
ProteinsMonomers: amino acids
Carbohydrates – polymer: polysaccharidesMonomers: monosaccharide
Lipid – Monomers – fatty acids
Nucleic Acids - polymers: DNA and RNAnucleuotides
Carbohydrates
Carbohydrate=Molecules made of sugars (glucose).
Found in: breads, grains, fruits and starchy foods.
Carbohydrates
Monomer= Monosaccharide
“Single sugar”
GlucoseDisaccharide= “double sugar”
Sucrose
Carbohydrates
Made of C, H, O.Uses for carbohydrates:
a. Energy-bodies first source of energy.
b. Structure- cell have carbohydrates in their cells instead of a skeleton.
Lipids (FATS!)
Lipid= Macromolecules that include fats, phospholipids, steroids and waxes.
Found in: body fat, steroids, waxes.
Lipids
Fats are water resistant
Made of: C, H, O.Monomers-Fatty
acids (have three long chains of carbon).
Lipids
Uses for lipids
a. Long term energy storage.
b. Water barriers
Protein
Protein= a molecule made up of amino acids.
Found in: muscle, eggs, dairy, enzymes, horns and many other living structures.
Protein
Made of: C, H, O, NMonomers: Amino acids (many different
kinds).
Protein
Uses for proteins:
a. Hair, hooves- structure
b. Muscle movement
c. Energy-the bodies last resort!
d. Enzymes-speed up body reactions
Nucleic Acids
Nucleic acids=A long chain of nucleotides.Found in: DNA and RNA (only)
Nucleic Acid
Made of: C, H, O, P, NMonomers-Nucleotides
Nucleic Acids
Uses for Nucleic Acids:
-Storing genetic information in DNA and RNA.

Reflection-Exit Slip
1. How did this video make you feel?
2. Do you think it was right for Caro to do the anorexia ad?
3. Do you think her body has an Carbs to burn? Fats? Muscle?
4. What may be affected by her lack of lipids?
