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?
