1. Macromolecules

2. Organic Compounds Macro = Large/Big
Macromolecules are large organic molecules.

3. Macromolecules Large organic molecules
Also called POLYMERS.
Smaller “building blocks” are called MONOMERS.
4 Examples:
1. Carbohydrates
2. Lipids
3. Proteins
4. Nucleic acids (DNA and RNA)

4. Carbohydrates

5. Carbohydrates Common Name: sugars
Major source of energy (and most immediate)

6. Carbohydrates Monomer: Monosaccharide (one sugar unit)
Examples: glucose (C6H12O6)
deoxyribose
ribose
Fructose
Galactose
glucose

7. Carbohydrates Disaccharide: two sugar unit Examples:
Sucrose (glucose+fructose)
Lactose (glucose+galactose)
Maltose (glucose+glucose)
glucose

8. Carbohydrates Polymer: Polysaccharide (many sugar units)
Examples: starch (bread, potatoes)
glycogen (beef muscle)
cellulose (lettuce, corn)
glucose
cellulose

9. Lipids

10. Lipids Common Name: Fats Not soluble in water (Hydro_____?)
“stores the most energy”
Monomer: Fatty Acids
Polymer: Triglycerides

11. Fatty Acids
There are two kinds of fatty acids you may see these on food labels:
1. Saturated fatty acids: no double bonds (bad)
2. Unsaturated fatty acids: double bonds (good) O
C-CH2-CH2-CH2-CH2-CH2-CH2-CH2-CH2-CH2-CH3 =
saturated O
C-CH2-CH2-CH2-CH
=CH-CH2-CH2-CH2-CH2-CH3 =
unsaturated

12. Lipids Four functions of lipids: 1. Long term energy storage
2. Protection against heat loss (insulation)
3. Protection against physical shock
4. Major component of membranes (phospholipids)

13. Proteins

14. Proteins Monomer: Amino acids Polymer: Polypeptide Chain
Three functions of proteins:
1. Storage
2. Transport
3. Enzymes

15. Nucleic Acids

16. Nucleic acids Two types:
a. Deoxyribonucleic acid (DNA- double stranded)
b. Ribonucleic acid (RNA-single strand)
Nucleic acids are composed of long chains of nucleotides (monomer).
Polymer- Polynucleotides
