Abstract

Though the vitalist group initially used the term “organic” for compounds produced only by organisms, it was later on used for carbon compounds. Wohler (1928) discovered that urea, which otherwise was thought to be produced only in the living beings, could also be produced in the laboratory from ammonia and bicarbonate. In 1897, German chemists Eduard Buchner and Hans Buchner demonstrated that fermentation could be carried out by the cell-free extract of yeast. These observations lead to the development of the science of biochemistry. In the early twentieth century, due to discovery of various metabolic pathways, biochemistry was dominated by organic chemistry, followed by enzymology and bioenergetics. Some of the analytical techniques which made study of biochemistry possible included isolation of organelles, high-performance liquid chromatography, electrophoresis, use of radioactive tracers, plant transformation techniques using Agrobacterium tumefaciens, gene silencing, forward genetics, reverse genetics, mass spectrometry, and DNA microarray, among others. With computational technology, it is now possible to have complete understanding of the interconnectivity of metabolic pathway.
