What are the physical and chemical properties of alkanes and cycloalkanes?
- 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
- 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.
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.
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
Draw the general structure of an amino acid and name the different groups they fall under
- Non-polar AA
- Polar neutral AA
- Polar Acidic AA
- Polar Basic AA
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
