Fischer, Emil Hermann
German chemist who produced synthetic sugars and, from these, various enzymes. His descriptions of the chemistry of the carbohydrates and peptides laid the foundations for the science of biochemistry. He was awarded the Nobel Prize for Chemistry in 1902 for his work on the synthesis of sugars and purine compounds.
In about 1882, Fischer began working on a group of compounds that included uric acid and caffeine. He realized that they were all related to a hitherto unknown substance, which he called purine. Over the next few years he synthesized about 130 related compounds, one of which was the first synthetic nucleotide. These studies led to the synthesis of powerful hypnotic drugs derived from barbituric acids (barbiturates).
