BIOCHEMISTRY

Biochemistry is the study of the chemicals (produced by or using processes which involve changes to atoms or molecules: processes) in living organisms. It deals with the structures (a particular arrangement of parts)and functions of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other bimolecular .Over the last 40 years biochemistry has become so successful at explaining living processes that now almost all areas of the life sciences from botany to medicine are engaged in biochemical research. Today the main focus of pure biochemistry is in understanding how biological molecules give rise to the processes that occur within living cells which in turn relates greatly to the study and understanding of whole organisms.
Among the vast number of different bimolecular, many are complex and large molecules (called polymers), which are composed of similar repeating subunits (called monomers). Each class of polymeric bimolecular has a different set of subunit types. For example, a proteins is a polymer whose subunits are selected from a set of 20 or more amino acids. Biochemistry studies the chemical properties of important biological molecules, like proteins, and in particular the chemistry of enzyme-catalyzed reaction.
Originally, it was generally believed that life was not subject to the laws of science the way non-life was. It was thought that only living beings could produce the molecules of life (from other, previously existing bimolecular). Then, in 1828, friedrich Wohler published a paper on the synthesis of urea , proving that organic compounds can be created artificially.
The dawn of biochemistry may have been the discovery of the first enzyme, diastase (today called amylase), in 1833 by Anselme Payne. Eduard Buchner contributed the first demonstration of a complex biochemical process outside of a cell in 1896: alcoholic fermentation in cell extracts of yeast. Although the term “biochemistry” seems to have been first used in 1882, it is generally accepted that the formal coinage of biochemistry occurred in 1903 by Carl Neuberger, a German chemist. Previously, this area would have been referred to as physiological chemistry.
