Question
1- Deducing Glycerophospholipid Structure from the Molar Ratio of its Components:
Complete hydrolysis of an unknown glycerophospholipid yields glycerol, fatty
acids (18:2(A9.12)), phosphoric acid, and ethanolamine in the molar ratio 1:2:1:1.
Draw the original structure of this unknown glycerophospholipid based on these
data.
2- Location of a Membrane Protein. The following observations are made of an
unknown membrane protein, X. This protein X can be extracted from plasma
membranes of erythrocytes after incubation of these membranes in a solution
containing an ionic detergent such as SDS. However, this protein X cannot be
extracted if the membranes are incubated in a solution containing a high
concentration of a sodium salt. Do the properties of X resemble those of an
integral or peripheral membrane protein? Explain.
