WEIRD WORDS? BREAK THEM DOWN! ORGANIC MACROMOLECULES = MONOMER = POLYMER = Today: Organic Macromolecules

Class, meet Molly Monomer. Yo!

In science, “poly” means MANY. Polymers are large molecules made up of many monomers

Monomers Polymer How many monomers does it take to make a polymer?

Monomers to Polymers

Polymer to Monomers

1. Carbohydrates 2. Proteins 3. Lipids 4. Nucleic Acids The 4 Main Types of Organic Macromolecules:

1. CARBOHYDRATES!

MONOMER (Building Block): monosaccharide 1. CARBOHYDRATES

What it Looks Like: 1. CARBOHYDRATES

What it’s Used For: 1. Energy source 1. CARBOHYDRATES

Examples: Glucose Glucose Glycogen Glycogen Starch Starch 1. CARBOHYDRATES

Memory Clue: Longest words go together! (Carbohydrate = Monosaccharide) 1. CARBOHYDRATES

 What are the building blocks of carbohydrates?  What are carbohydrates used for?  When might you want to eat a lot of carbohydrates? CHECK FOR UNDERSTANDING

2. LIPIDS!

Monomer (Building Block): fatty acid 2. LIPIDS!
