The Importance of Organic Chemistry in Medicine
CS316: Advanced Organic Chemistry
Prepared by Lynn McMullin at NSAC
Organic chemistry has been highly disregarded as a
discipline of importance for medical and premedical
curriculums. At present, however, people are
beginning to make the connection between organic
chemistry and its importance in the medical field.
New curriculums are being designed that unite organic
chemistry and biomedical processes. Task forces
consisting of chemistry and biology researchers and
professors have been formed to design curriculums that
incorporate organic chemistry courses to suit the
needs of students in medical fields. These task forces
are attempting to develop a practical, comprehensive
approach to organic chemistry as it applies to medicine.
Organic chemistry is essential in biological and medical
fields. All living organisms are composed of abundances
of organic substances. Evolution of life has been
postulated to have been developed from one single organic
compound called a nucleotide. Nucleotides polymerize, or
join together to form the building blocks of all life,
DNA (deoxyribonucleic acid).
Organic compounds constitute various substances in the
body which are vital for life to be sustained. Proteins,
carbohydrates and lipids are organic compounds that
contribute to the structure of the human body.
Organic compounds also make up enzymes and catalysts
that are mandatory for essential biological processes
to occur. Also, organic compounds are responsible for
governing ion transport channels in the cell which
function in carrying information from one cell to another
and mediating cell to cell communication. Failure of ion
transport may result in failure of important biological
processes in the body.
Pharmaceuticals are also comprised mainly of organic
compounds. What doctor would be efficient if he or she
was not familiar with the structure and function of the
drugs they were administering? Organic chemistry of
pharmaceuticals must be understood to properly prescribe
a drug to a patient.
The function of organic processes in the body must also
be known by the doctor even before they attempt to
administer any drugs. Many medical disorders are due
to disruption of organic molecules in the body: for
example, hemophilia. This is a disease in which
caroxyglutamic acid is deficient in the body. This
organic compound is essential for blood clotting to
occur within the body. People who lack this substance
may die due to a minor cut or small bruise. This
demonstrates the importance of organic compounds in
the body.
Carbon monoxide poisoning is an example of a very
simple, yet extremely toxic organic compound that even
in small quantities can cause death. Many toxic
substances are of organic descent. Doctors must be
able to determine the effects of these toxic substances
in the body, recognize the symptoms they are associated
with, and prescribe the appropriate pharmaceutical to
combat the poison.
It is evident that organic molecules are essential for
the sustenance of all life. Understanding these compounds
is crucial in the medical field not only to understand
basic biological functions, but also to predict scenarios
in the body which may be due to disruption of organic
substances, or adverse reactions due to foreign organic
substances in the body. Complete medical efficiency will
only be achieved when the science of organic chemistry
is understood.

其實我小兒最近有留意中大醫科的收生情況,中大醫學院似乎考慮把40分的考生也納入考慮的範圍之內!其實這也在所難免,去年有1200多人把中大醫學放在band A,今年競爭雖然激烈,但數量也只是去年一半左右,只有600人,當中還包括一些把港大醫學放在首選的同學,所以我也估計中大把收生分數拉得那麼高會出現收生不足的情況
