Fischer Esterification: Synthesis of Isoamyl Acetate (Banana
Oil)
4)
a) What is the role of sulfuric acid in the reaction?
b) Why is the mixture extracted with sodium bicarbonate? Your
answer should include a chemical equation to explain why gas
bubbles are observed and identify the gas.
c) What is brine and why is it used?
Pyridine is used in the synthesis of tosyl chloride from tosic
acid, and also in reactions that involve tosylate esters. What
characteristic of pyridine makes it the base of choice for these
reactions? What might happen if a base were used that did not have
this particular characteristic?
Compare the regulation of the pyrimidine synthesis
pathway in bacteria and mammals. What is similar, and what is
different? Consider the enzymes involved, and the reactions they
carry out (what happens in the reactions), as well as the kind of
regulation. What is one of the enzymes “famous” for?
Explain.
.
Why are synthesis and decomposition reactions important in the
body? Why are reversible reactions important in the body? What role
does negative feedback serve regarding homeostasis? Name 3 positive
feedback mechanisms of the body
Study dehydration synthesis and hydrolysis. Why are these
reactions called dehydration synthesis if dehydration means to
remove water and synthesis means to build? What do you think
happens to large molecules during hydrolysis reactions?
What is similar about the reactions of the salivary and lacrimal
glands, kidney, bladder and digestive organs?
How do these organs react to Parasympathetic Nervous System
Output?(remember the SLUDD reactions)
2) what is an adrenergic receptor? Distinguish between alpha
and beta adrenergic receptor and their actions?
Compare and contrast the accuracy of:
DNA replication
RNA synthesis
Protein synthesis
What mechanisms are used to ensure the fidelity of each of these
processes? in writing no diagrams or pictures
