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


  1. What are the physical and chemical properties of alkanes and cycloalkanes?
    • Physical
    • 1. They are insoluble in water and soluble in nonpolar solvents
    • 2. They are less dense than water
    • 3. The BP increases as the carbon-chain increases but decreases with branching

    • Chemical
    • 1. They are both flammable and readily undergo combustion. Their products are CO2 and H2O.
    • 2. They both undergo halogenation where hydrogen is replaced by a halogen. This process requires heat or light to occur.
  2. What are the characteristics and uses of formaldehyde and oxalic acid?
    • Formaldehyde is an aldehyde and has a pungent odor. It is used as a disinfectant and kills bacteria flora in the GI.
    • Oxalic acid is a carboxylic acid and contains a tart taste. It is used to remove rust and ink stains.
  3. What are the 5 types of lipids and how do they function?
    • 1. Energy storage lipids: stored for use when energy demand is high.
    • 2. Membrane lipids: Structural components of cell membrane.
    • 3. Emulsification lipids: Stabilize and dispense water insoluble materials in aqueous solution.
    • 4. Messenger lipids: Regulatory lipids that act there they are synthesized or other locations via the blood stream.
    • 5. Protective coating lipids: Protective and lubricating functions
  4. Draw the general structure of an amino acid and name the different groups they fall under
    • Groups:
    • Non-polar AA
    • Polar neutral AA
    • Polar Acidic AA
    • Polar Basic AA
  5. What makes recombinant DNA different from normal DNA and why are plasmids important to them? How is recombinant DNA obtained?
    • Recombinant DNA contains a foreign gene, meaning it contains genetic material from 2 different organisms.
    • Plasmids serve as the host for the foreign gene.
    • Recombinant DNA is obtained through the following:
    • Cell membrane dissolution
    • Cleavage of plasma DNA
    • Gene removal from other organisms
    • Gene-plasma splicing
    • Isolation of plasmid function
