Louis Pasteur Louis Pasteur: Greatest Achievements Louis Pasteur was one of the most important scientists of our time. The foundation of our knowledge about health and disease comes from the discoveries of this one man.
He made many discoveries and solutions for problems of the every day life that are still in effect today. When he was five years old his family moved to Arbois where he grew up with his father, mother, and three sisters.
While attending primary school Pasteur was only an average student. Some considered him to be slow because he worked so hard on an exercise problem to make sure that he had the right answer.
With this encouragement Pasteur became a very good student. The principal suggested that he aim to attend Ecole Normale in Paris where he could become a professor at one of the great universities, however his father felt that this was far-fetched and preferred that Pasteur attend a more local school Burton, Although his father had other plans for him, Pasteur had the opportunity to attend a preparatory school in Paris before going on to Ecole Normale, however when he got to Paris he The future of bio pasteur essay very homesick and his father soon arrived to take him home.
After returning to Arbois Pasteur attended a local school named Besancon where he worked very hard and became one of the top students in his class. In Pasteur passed the admission tests to attend Ecole Normale however he was rated fifteenth of twenty-two candidates and this was not good enough to satisfy him.
He continued to study and finally in Pasteur sailed through his admission tests and was awarded fourth place among the other candidates Burton, Although Pasteur is sometimes considered to be the father of microbiology and immunology, he actually launched his career as a chemist who studied the shapes of organic crystals.
Crystallography was just emerging as a branch of chemistry and his project was to crystalize a number of organic compounds. While working on this project he began to work with tartaric acid and racemic acid. Earlier these two acids had been determined to be identical, however Pasteur found that in solution they had a striking difference which was that tartaric acid rotated a beam of polarized light whereas the racemic acid did not.
When looking at them under the microscope he found that the crystals of the tartaric acid were identical while the crystals of the racemic acid were of two types, almost identical but not quite.
One type was mirroring the other the way the right hand mirrors the left hand Cohn, par. After discovering the different types of crystals, Pasteur then took a dissecting needle and separated the left and right crystals from each other under the microscope.
He then showed that in solution one form rotated light to the left and the other to the right. This proved that organic molecules with the same chemical composition can exist in space in unique stereo specific forms. With this discovery Pasteur launched the new science of stereo chemistry.
He proposed that asymmetrical molecules were indicative of living processes.

Because of this we know today that proteins of higher animals are made up only of the amino acids that exist in the left-hand form. The mirror image right-hand amino acids are not used in human or animal cells.
Just like our cells only burn the right-hand form of sugar, not the left-hand that can be made in a test tube Cohn, par.
In Pasteur was approached with a problem by a Monsieur Bigo. Monsieur Bigo manufactured alcohol from beets and recently his beet juice had been spoiling instead of producing alcohol. Pasteur chose to look into the problem because it had something to do with the new concept of fermentation, which he had just become very curious about.
To make alcohol the workers added yeast to a vat of fresh beet juice. Eventually the yeast formed a mold and then little bubbles appeared in the juice and it was said to be fermenting. If it was "healthy" then it would produce alcohol, but sometimes it turned sour and Monsieur Bigo had to throw it away.
Pasteur collected samples of the juice and also deposits from the vats.Today, Pasteur is often regarded as the Father of Germ Theory, which is the theory that germs cause diseases, and bacteriology, the study of bacteria, together with Robert Koch. Creationism and Pasteur. Henry Morris, the founder of modern creationism, wrote: Louis Pasteur is one of the greatest names in the history of science and medicine, chiefly because of his establishment of the germ theory of disease and his conclusive demolition of the then-prevalent evolutionary concept of spontaneous generation.
