The flashcards below were created by user ckluckner on FreezingBlue Flashcards. What would you like to do?


  1. What compounds are "organic molecules?"
    • Compounds that contain hydrogen-carbon bonds.
  2. Hydrophillic Macromolecule Property
    "Water loving" (Dissolves in water)
  3. Hydrophobic Macromolecule Property
    "Water fearing" (Does NOT dissolve in water)
  4. Macromolecules properties depend on:
    Size and Shape
  5. Macromolecules (Definition and explanation of structure)
    Def: Large Organic Compounds/Molecules

    • Structure:
    • Creation- remove water + dehydration
    • Breaking- Add water (Hydrolysis)
  6. Classes of Macromolecules
    • Carbs
    • Lipids
    • Proteins
  7. Types of Carbohydrates (Sugars)
    • "Hydrophillic"
    • 1. Monosaccharide - one sugar
    • 2. Polysaccharide- more than one sugar unit together
  8. Protein Polymer (def)
    Long chain of Amino Acids (AA-AA-AA-AA)
  9. Protein Functions
    • Enzymes
    • Transporters
    • Signals (Hormones)
    • Defense (Antibodies)
    • Storage
  10. Protein Shapes
    • (They build on each other)
    • 1. Primary level: Amino Acid Chain (polypeptide)
    • 2. Secondary Level: Polypeptide chain becomes "telephone wire" (alphahelix) or "mountains" (Beta sheets)
    • 3. Tertiary Level: combination of alphahelix and beta sheets
    • 4. Quartnery level: combining tertiary shapes together 88
  11. Lipids (Fats) Functions
    • Energy Storage
    • Insulation
  12. 2 Types of Lipids
    • Unsaturated
    • Saturated
  13. Unsaturated Lipids Qualities
    • "Kinks" in structure (not tightly packed)
    • Liquid at room temp
    • Healthy Fats (Veggie oil, Canola Oil, Olive Oil)
  14. Saturated Fats Qualities
    • "No Kinks" in structure (tightly packed)
    • Solid at room temp
    • Unhealthy (eggs, ice cream, steaks, butter)
  15. What is a Nucleic Acid?
    A Polymer of Nucleotides
  16. Nucleotide Diagram with 3 components
  17. 2 Types of Nucleic Acid
    • DNA (Deoxyribonucleic Acid)
    • RNA (Ribonucleic Acid)
  18. DNA Qualities and 4 Bases
    • Shown as "2 strands"
    • Nitrogenous
    • 4 Bases:
    • 1. Adenine
    • 2. Guanine
    • 3. Cytosine

    *4. Thymine (different from RNA)
  19. RNA Qualities and 4 Bases
    • Shown as "1 strand"
    • Nitrogenous
    • 4 Bases:
    • 1. Adenine
    • 2.Guanine
    • 3. Cytosine

    *4. Uracil (Different from DNA)
