Biomolecules

1
Biomolecules

• Molecular basis of life

2
Polymers

• mer means unit
• mono means one
• Monomer-one unit
• poly means many
• Polymer-many units
• Polymers are made of many monomers

3
Biomolecules

• Four majors types of Biomolecules
• Carbohydrates
• Lipids
• Proteins
• Nucleic Acids

4
Carbohydrates

• Monomer-simple sugar like glucose
• Stores energy and provides structure
• Simple Sugars
• Glycogen
• Starch in plants

5
Candy Question

• What are lipids?

6
Lipids

• Used to store energy
• One gram of fat contains over twice the energy of
  one gram of carbohydrate
• Important categories
• Fats, Oils, Waxes
• Steroids
• Phospholipids
• Structure
• Glycerol molecule 3 fatty acids

7
Proteins

• Monomer-amino acid
• Provide structure and help chemical reactions
• Enzymes-speed up chemical reactions
