An unknown compound is one of the four compounds shown below. It is an amphipathic lipid, it immediately decolorizes bromine solution, and readily reacts with aqueous solution of sodium hydroxide. The pain and swelling caused by arthritis and related illnesses results from the production of this compound in the affected tissues. Based upon the information provided, answer the tolowing questions (A- E) (5 points) 6. Ho-CH--ck CH-N-C-R A) All the compounds pictured are amphipathic molecules. Describe the term amphipathic Give an example of a non-amphipathic lipid. Solution a) An amphipathic molecule is the one which comprises of two parts : All the lipids molecules found are amphipathic in a cell membrane. b) Out of all the four compounds given in the question the one responsible for controling the development of sex organs and secondary sexual characteristic is the compound C. The name associated with this type of compound is ANDROGENS. Yes androgens will react with NaBH 4 and reduces 1-carbonyl group of 3-deoxy androgens to form aromatase inhibitors having a 19-hydroxy group. c) The compound A can be identified as local hormone. The name of the compound is ALPROSTADIL. These molecules are called local molecule these are produced by cells and to either neighboring cells(i.e. local to their neghbourhood ) or the same tupe of cells that are responsible for their production. These hormones are very quickly inactivated.These are large group of signalling molecules and are released during phisical activity like exercise and running. These hormones donot circulate within the blood thus are local to their production area. d) Compound B is a major component of biological membrane. Yes these compounds are hydrolysable due to the fact that they contain ester group. These compounds are hydrolusable because tehy contain funtional group ester. .

1. An unknown compound is one of the four compounds shown below. It is an amphipathic lipid, it
immediately decolorizes bromine solution, and readily reacts with aqueous solution of sodium
hydroxide. The pain and swelling caused by arthritis and related illnesses results from the
production of this compound in the affected tissues. Based upon the information provided,
answer the tolowing questions (A- E) (5 points) 6. Ho-CH--ck CH-N-C-R A) All the compounds
pictured are amphipathic molecules. Describe the term amphipathic Give an example of a non-
amphipathic lipid.
Solution
a) An amphipathic molecule is the one which comprises of two parts :
All the lipids molecules found are amphipathic in a cell membrane.
b) Out of all the four compounds given in the question the one responsible for controling the
development of sex organs and secondary sexual characteristic is the compound C. The name
associated with this type of compound is ANDROGENS.
Yes androgens will react with NaBH 4 and reduces 1-carbonyl group of 3-deoxy androgens to
form aromatase inhibitors having a 19-hydroxy group.
c) The compound A can be identified as local hormone. The name of the compound is
ALPROSTADIL. These molecules are called local molecule these are produced by cells and to
either neighboring cells(i.e. local to their neghbourhood ) or the same tupe of cells that are
responsible for their production. These hormones are very quickly inactivated.These are large
group of signalling molecules and are released during phisical activity like exercise and running.
These hormones donot circulate within the blood thus are local to their production area.
d) Compound B is a major component of biological membrane.
Yes these compounds are hydrolysable due to the fact that they contain ester group. These
compounds are hydrolusable because tehy contain funtional group ester.
