  1. BIOL 1441-030 Wed 11:00 – 12:50 LS 200 BIOL 1441-033 Thu 3:00 – 4:50 LS 207 BIOL 1441-037 Fri 11:00 – 12:50 LS 200 Heath Blackmon LS 459 Office Hours: 10:30-12:00 Tue and Thu heath.blackmon@mavs.uta.edu

  2. Macromolecules Diverse molecules that serve a variety of purposes in living organisms

  3. CARBOHYDRATESLIPIDS PROTEINSNUCLEIC ACIDS*

  4. Carbohydrates • Made of Carbon, Hydrogen, Oxygen • Monosaccharide • Glucose, fructose, ribose • Disaccharide • Lactose, Sucrose • Polysaccharide • “Many Sugars”

  5. Carbohydrates • Polysaccharides • Starch • Glucose storage • Glycogen • Glucose storage • Cellulose • structural

  6. Carbohydrates • How do you break up large sugars? • Hydrolysis • With use of enzymes, break down complex starches to glucose, in presence of water. • Ex: Seed growth, beer production

  7. Lipids • Made of Carbon and Hydrogen • Insoluble in water • Ex: Oils, fats • Found in plants and animals

  8. Proteins • Made of tightly bound Amino Acids • Peptide bonds • Structure • Primary • Secondary • Tertiary • Quaternary

  9. Tests to be performed today Sugar, Starch, Lipid, Protein

  10. Sugar Test • Benedict’s Reagent • Glucose vs. Sucrose • Tests for presence of simple sugars (monosacchride) • Record results

  11. Starch Test • Iodine Reagent (iodine potassium iodide) • Mix with potato starch in test tube • Record results

  12. Hydrolysis • Breaking up sugars with water and acid • Test samples with Benedict's test and Iodine test • Record results

  13. Lipid Test • Brown Paper test • Record Results

  14. Protein Test • Biuret reagent – protein indicator • Albumin – Egg protein • Record Results

  15. Macromolecules in Food • Separation of Butter • Lipid Layer and Protein Layer of butter • Perform tests on the two layers and regular butter • Tests with food • Perform the tests on Banana, Coconut, Milk, Peanut, and Potato

  16. Lab Manual 52-75 Conversions and Scientific Notation Difference between a monosachride and disachride Monosachrides are simple sugars Disachrides have two simple sugars joined together Carbohydrates are long chains of sugars An example of a way that we use macromolecules: Lipids – cell membranes Proteins – enzymes (hemoglobin) Carbohydrates – energy storage Nucleic Acids – DNA Lab Manual pp 52-75
