Experiment:
Lab goals
Isolate an enantiopure sample of phenylsuccinic acid from a
racemic mixture
Assess the enantiopurity of the recovered material using
polarimetry experiment
Procedure
1. Selectively preiciptate the (+) enantiomer of phenylsuccinic
acid using L(–) proline resolving agent
2. Remove the (–) proline (resolving agent) from the
precipitate by washing with acid solution (HCl)
3. Determine the enantiomeric excess of (+)-phenylsuccinic acid
in the precipitate using polarimetry
4. Collect your enantiomerically enriched product in the
(+)-phenylsuccinic acid container

Is it possible to sequence rRNA directly, that is, using the ribosome rather than the DNA from the nucleus? For example, this paper, Complete nucleotide sequence of a 16s rRNA gene from E. coli, suggests that it uses DNA to find the sequence. Would it be possible to isolate the rRNA and derive the sequence from that?

What is the limiting reagent in this experiment? Acetophenone or
aqueous bleach?
1. Add about 1.0 g (measured accurately) of acetophenone to 40 mL of the bleach solution (5% NaCl in water - this reactant should be included in your table of reagents!) in a 100 mL round bottom flask equipped with a magnetic stirrer. Clamp the flask in the fume hood above a stir plate. 2. After the initial reaction has subsided, boil the reaction mixture gently for 5...
