Presentation Transcript

  1. Macromolecules and Your Body Anatomy

  2. Carbohydrates • Three main carbohydrates in body • Glucose (stores energy) • Glycogen (stores energy) • Ribose (expression of hereditary information)

  3. Lipids • Four main lipids that are important to us • Triglycerides • Phospholipids • Steriods • Prostaglandins/ Eicosanoids

  4. Triglycerides • Store energy • Butter, olive oil • Get a lot from your diet

  5. Phospholipids • Lecithin and Cephalin • Form cell membranes

  6. Steriods • Cortoicosteroids (cortisol, cortisone, corticosterone) • Synthesis hormones and help form membranes

  7. Prostaglandins & Eicosanoids • Regulating actions of hormones • Help immune system • Influences inflammatory response • Causes contraction of smooth muscle for labor • Contributes to production of mucus in stomach

  8. Proteins • Functional and structural

  9. Functional Proteins • Regulate chemical reactions

  10. Structural Proteins • Form part of the tissues that provide mechanical support to the part of the body where they are located

  11. Nucleic Acids • DNA and RNA

  12. DNA • Genetic code and information • Ensures daughter cells inherit data from parent cells • Code the ways proteins turn genes on and off • Needed to form mRNA

  13. RNA • Carries genetic information • Catalyzes biochemical reactions • Adapter molecule in protein synthesis • Structural molecules in cellular organelles • mRNA • tRNA • rRNA • snRNA (catalyze reactions with mRNA) • gRNA (edits RNA)

  14. Combinations of Macromolecules • Glycoproteins • Mannose and galactose • Regulate chemical reactions (similar function to functional proteins)

  15. Combinations of Macromolecules • Proteoglycans • Important for lubrication (increase thickness of fluids)

  16. Combinations of Macromolecules • Lipoproteins • Transport lipids in blood

  17. Combinations of Macromolecules • Glycolipids • Cerebrosides (in myelin sheaths of nerve fibers) • Cell membranes

  18. Combinations of Macromolecules • Ribonucleoproteins • Have enzyme like properties (slicing mRNA  snRNPs)
