1. Biomolecules

2. Four Organic Compounds:
Carbohydrates
Lipids
Proteins
Nucleic Acids
Why organic?

3. Carbohydrates Polymer Monomer monosaccharide Function body’s primary
(Macromolecule)
Carbohydrates
Monomer
monosaccharide
Function
body’s primary
source of energy
Examples
glycogen (animals); starch (plants)
cellulose (plant cell wall)
Diagram
glucose
molecule
C6H12O6
1: 2: 1 Ratio
Elements:
C,H,O

4. Three Types of Carbohydrates:
Monosaccharide – “mono” means one
a single sugar
Disaccharide – “di” means two
two sugars
Polysaccharide – “poly” means many
sugars

5. Lipids Polymer Monomer fatty acids & glycerol Function
(Macromolecule)
Lipids
Monomer

Examples
fats, oils, waxes, steroids, cholesterol
phospholipids (cell membrane)
Diagram
Elements:
C,H,O

6. Common Lipid Structures
Phospholipid Triglyceride
Saturated
(solid lipid)
Unsaturated
(liquid lipid)

7. needed for growth & repair
Polymer
(Macromolecule)
Proteins
Monomer
amino acids
Function
needed for growth & repair
Examples
