Biochemistry Wikipedia. Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism, biochemical processes give rise to the complexity of life. Over the last decades of the 2. Decision Tree Excel Add-In there. Today, the main focus of pure biochemistry is on understanding how biological molecules give rise to the processes that occur within living cells,3 which in turn relates greatly to the study and understanding of tissues, organs, and whole organisms4that is, all of biology. Biochemistry is closely related to molecular biology, the study of the molecular mechanisms by which genetic information encoded in DNA is able to result in the processes of life. Depending on the exact definition of the terms used, molecular biology can be thought of as a branch of biochemistry, or biochemistry as a tool with which to investigate and study molecular biology. Much of biochemistry deals with the structures, functions and interactions of biological macromolecules, such as proteins, nucleic acids, carbohydrates and lipids, which provide the structure of cells and perform many of the functions associated with life. The chemistry of the cell also depends on the reactions of smaller molecules and ions. These can be inorganic, for example water and metal ions, or organic, for example the amino acids, which are used to synthesize proteins. The mechanisms by which cells harness energy from their environment via chemical reactions are known as metabolism.

In medicine, biochemists investigate the causes and cures of diseases. In nutrition, they study how to maintain health wellness and study the effects of nutritional deficiencies. In agriculture, biochemists investigate soil and fertilizers, and try to discover ways to improve crop cultivation, crop storage and pest control. HistoryeditAt its broadest definition, biochemistry can be seen as a study of the components, and composition of living things and how they come together to become life, and the history of biochemistry may therefore go back as far as the ancient Greeks. However, biochemistry as a specific scientific discipline has its beginning sometime in the 1. Some argued that the beginning of biochemistry may have been the discovery of the first enzyme, diastase today called amylase, in 1. Anselme Payen,1. Eduard Buchners first demonstration of a complex biochemical process alcoholic fermentation in cell free extracts in 1. Some might also point as its beginning to the influential 1. Justus von Liebig, Animal chemistry, or, Organic chemistry in its applications to physiology and pathology, which presented a chemical theory of metabolism,1. Antoine Lavoisier.

F. Gowland Hopkins on enzymes and the dynamic nature of biochemistry. The term biochemistry itself is derived from a combination of biology and chemistry. In 1. 87. 7, Felix Hoppe Seyler used the term biochemie in German as a synonym for physiological chemistry in the foreword to the first issue of Zeitschrift fr Physiologische Chemie Journal of Physiological Chemistry where he argued for the setting up of institutes dedicated to this field of study. The German chemist. Carl Neuberg however is often cited to have coined the word in 1. Franz Hofmeister. It was once generally believed that life and its materials had some essential property or substance often referred to as the vital principle distinct from any found in non living matter, and it was thought that only living beings could produce the molecules of life. Then, in 1. 82. 8, Friedrich Whler published a paper on the synthesis of urea, proving that organic compounds can be created artificially. Since then, biochemistry has advanced, especially since the mid 2. X ray diffraction, dual polarisation interferometry, NMR spectroscopy, radioisotopic labeling, electron microscopy, and molecular dynamics simulations. These techniques allowed for the discovery and detailed analysis of many molecules and metabolic pathways of the cell, such as glycolysis and the Krebs cycle citric acid cycle. Another significant historic event in biochemistry is the discovery of the gene and its role in the transfer of information in the cell. This part of biochemistry is often called molecular biology. In the 1. 95. 0s, James D. Watson, Francis Crick, Rosalind Franklin, and Maurice Wilkins were instrumental in solving DNA structure and suggesting its relationship with genetic transfer of information. In 1. 95. 8, George Beadle and Edward Tatum received the Nobel Prize for work in fungi showing that one gene produces one enzyme. In 1. 98. 8, Colin Pitchfork was the first person convicted of murder with DNA evidence, which led to the growth of forensic science. More recently, Andrew Z. Fire and Craig C. Mello received the 2. Nobel Prize for discovering the role of RNA interference RNAi, in the silencing of gene expression. Starting materials the chemical elements of lifeedit.

Most organisms share element needs, but there are a few differences between plants and animals. For example, ocean algae use bromine, but land plants and animals seem to need none. All animals require sodium, but some plants do not. Plants need boron and silicon, but animals may not or may need ultra small amounts. Just six elementscarbon, hydrogen, nitrogen, oxygen, calcium, and phosphorusmake up almost 9. In addition to the six major elements that compose most of the human body, humans require smaller amounts of possibly 1. BiomoleculeseditThe four main classes of molecules in biochemistry often called biomolecules are carbohydrates, lipids, proteins, and nucleic acids. Many biological molecules are polymers in this terminology, monomers are relatively small micromolecules that are linked together to create large macromolecules known as polymers. When monomers are linked together to synthesize a biological polymer, they undergo a process called dehydration synthesis. Different macromolecules can assemble in larger complexes, often needed for biological activity. CarbohydrateseditThe function of carbohydrates includes energy storage and providing structure.

There are more carbohydrates on Earth than any other known type of biomolecule they are used to store energy and genetic information, as well as play important roles in cell to cell interactions and communications. The simplest type of carbohydrate is a monosaccharide, which among other properties contains carbon, hydrogen, and oxygen, mostly in a ratio of 1 2 1 generalized formula Cn. H2n.
