Presentation Transcript

  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. Blank 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

  8. Candy Question What is the last type of biomolecule? What is a common name for this type of biomolecule?

  9. Nucleic Acids • Monomer-Nucleotide • Stores and transmits genetic information • Two types • Deoxyribonucleic acid – DNA • Ribonucleic acid - RNA

  10. Candy Question What is the relationship between a monomer and a polymer?

  11. Candy Question Without looking, name the four types of biomolecules.

  12. Candy Question What do enzymes do?
