 Biochemistry - Wikipedia, the free encyclopedia
Biochemistry is the study of the structure and function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules.
The biochemistry of cell metabolism and the endocrine system has been extensively described.
Today, the findings of biochemistry are used in many areas, from genetics to molecular biology and from agriculture to medicine.

 Receptor (biochemistry) - Wikipedia, the free encyclopedia
In biochemistry, a receptor is a protein on the cell membrane or within the cytoplasm or cell nucleus that binds to a specific factor (a ligand), such as a neurotransmitter, hormone, or other substance, and initiates the cellular response to the ligand.
Most hormone genes contain a short sequence that signals to the cell whether it needs to be transported to the cell membrane or it is to remain in the cytoplasm.
These receptors are either coupled to G proteins or possess enzyme or ion channel activity that allow the activation of signal transduction pathways in response to the activation by the ligand.

Biochemistry is the study of the chemical reactions and interactions that take place in living organisms, especially the structure and function of their components, such as proteins, carbohydrates, lipids, nucleic acids, and small molecules present in cells.
Biochemistry could also (now) be defined as being the chemistry of enzyme-mediated reactions, whether in vivo or in the test tube, with natural or artificially modified enzymes and other chemicals.
For historical reasons, the biochemistry of metabolism has been one of the most extensively described aspect of the cell.

The biochemistry of cell metabolism has been extensively described.
In 1828, Friedrich Wöhler published a paper about the synthesis of urea, proving that organic compounds can be created artificially, in contrast to the common belief of the time that organic compounds can only be made by living organisms.

Biochemistry is the study of the chemicals, chemical reactions and chemical interactions that take place in living organisms.
Biochemistry is focused on the structure and function of cellularcomponents, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules.
Since then, biochemistry has advanced, especially since the mid- 20th century, with the development of new techniques such as chromatography, X-ray diffraction, NMR, radioisotopic labelling, electron microscopy and moleculardynamics simulations.

The determination of single cell functions was difficult and limited in the past because microelectrodes had to be introduced into single cells e.g.
Cell functions (Tab.1) can be determined at high speed in flow cytometers with a multitude of biochemically specific, non toxic fluorescent indicator molecules close to the in-vivo state and without prolonged exposure to unusual light levels.

 Cell and molecular biology definitions with Beelib, the online biology dictionary.   (Site not responding. Last check: 2007-11-03)
The biology Terms of the Bee cell biology dictionary relate to the fundamental concepts and essential processes involved in cell structure, activities, life and death (a cell diagram is often presented in the cell biology article), and the main technical approaches available in Molecular Biology.
Various thematic approaches have thus been used to select the Terms to be defined: cell signaling, membrane and intracellular cell receptors, virology, main biochemical compounds and processes they control, principles of immunology, main molecular biology techniques.
Indeed, the proliferation of new terms in scientific and clinical fields which are highly descriptive makes it harder and harder to control and understand the scientific and technical terminology used in biomedical research, teaching of biology and medicine, and clinical activities.
