Chapter 20.4, Problem 6P
Interpretation Introduction
Interpretation:
Difference in the amino acid composition of integral and peripheral membrane protein has to be given.
Concept Introduction:
Phosphoglycerides form membranes by arranging themselves in a lipid bilayer. The polar heads of the phosphoglycerides are on both surfaces of the bilayer and fatty acids form the interior of the bilayer.

1. Using Online resources and chemical structures hand draw four different
organic compounds (not those already shown in your handout) that are
chiral, optically active (a pair of enantiomers will count as one). Pay attention
to correct stereochemistry
2. Write or type a short paragraph to Discuss the stereochemical relationship
between the four compounds.

- Could you crystallize one enantiomer of mandelic acid from a racemic mixture (using the typical achiral solvents found in our lab) without preparing a diastereomeric salt? Why or why not? No, because both enantiomers have the same solubility in achiral solvents. than the other. ооо Yes, because one enantiomer has a higher melting point No, because both enantiomers are liquids.
