biochemistry
1. the chemistry of life or biochemistry as chemists call it is an area in which classical
fields of chemistry and biology meet. it can be called “molecular biology”. biochemistry
is the study of the structures and reactions of the thousands of compounds involved in
life process. biochemistry is considered to be the most complex area of chemistry.
2. living things represent the most efficient sophisticated, compact chemical “factories”
ever known. how, for example, do cells of the body know when to divide and multiply
into new cells having the same characteristics as the original cells? when the body is
afflicted by disease or by a wound how does the body protect itself and repair the
damage? we know these processes to involve thousands of different chemical
compounds.
3. when we compare the nervous system to man-made electronic computers the
efficiency and complexity of the biological systems become even more impressive.
despite great advances in computer technology, the greatest computer ever built is
almost insignificant being compared to a human brain weighing little more than a
kilogram. a computer can perform mathematical operations millions of times faster than
a person but what the nervous system can do! for example, it can cause your arm to
reach out and touch an object. the brain can translate signals from the retina of the
eyes into three dimensional colour images. it can translate a series of frequencies
detected by the ear into thoughts whereas a computer can only perform operations
being programmed by a person. as to the storage capacity the brain really wins out.
the largest computers have storage capacity of about one million “words” but some
experts believe the brain to store up all the signals it receives.
4. the chemical processes of our bodies involve enormously complex sequences of
reactions, details of these processes being far from complete understanding.
nevertheless the great progress has been made in our understanding of the processes
that occur in the body.
5. the first half of this century might be termed the golden age of physics because so
many discoveries in understanding the structure of molecules, atoms and nuclei were
made. by the same virtue we may be in the midst of a golden age in biochemistry. the
next few years of research may bring much increased understanding of chemical
processes in cells.
