List two classes of compounds derived from arachidonic acid. Suggest some reasons for the amount of biomedical research devoted to these compounds.

7. Structure and formation reactions of phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine.

compare the structures of the peptide neurotransmitters Met-enkephalin and Leu-enkephalin

The affinity of hemagglutinin for sialic acid is quite low, with a Kd of approximately 5 mM. How does efficient attachment occur with such a low-affinity interaction?

Draw the structure of the phosphatidic acid group in phosphatidylcholine (or give its stoichiometry).

Give the name and structure of: Ceramide Shiphingomyelin Ganglioside

On Dimyristoyl phosphatidylserine, Palmytoyl-Oleoyl Phosphatidylcholine and Sphingomyelin, What is the capacity of each of these to form hydrogen bonds with its neighbours

Describe the differences between lecithin and cephalin. Draw the structure of a glycerophospholipid containing two molecules of stearic acid and ethanolamine.

Tricyclic, anti-depressant drugs were developed from the observation that some tricyclic, anti-psychotic drugs elevated a patient’s mood.          Identify the structural features of a tricyclic drug that were found to affect its action as a pure anti-depressant or a mixed anti-psychotic/anti-depressant agent and comment on the structural modifications that can be made to such an anti-depressant drug whilst retaining the essential pharmacophore.
