1 CHAPTER 5: The Structure & Function of Macromolecules
OBJECTIVES: Understand Structure and Function of Carbohydrates Proteins Nucleic Acids Lipids Levels of protein folding

2 Polymers Most macromolecules are polymers build from monomers.
Starch is built from glucose monomers Proteins are built from amino acid monomers VIDEO

3 Joining Polymers Condensation or dehydration reaction: Hydrolysis:
Creating a polymer by removing a water Hydrolysis: Water used to split polymers into smaller portions Hydro - Water Lysis – Cut or split

4 Carbohydrates Fuel and Building Material
Simple sugars ( glucose, fructose, galactose) Polymers: starch. All exist in ratio of 1:2:1 C:H:0 Monosaccharides: Monomers of carbohydrates Glucose, ribose Polysaccharides: polymers of monosaccharides Starch, cellulose, glycogen

5 Glycosidic Linkage

6 Energy Storage & Structural Support
Energy storage polysaccharides Starch: Plants Glycogen: Animals, muscle and liver cells Structural Support Cellulose: Component of plant cell walls Chitin: Exoskeleton of arthropods, lobsters, cockroaches “Crunch”

7 Chitin
