	Britain.tv Wikipedia - Redox
		This can be a simple redox process, such as the oxidation of carbon to yield carbon dioxide, it could be the reduction of carbon by hydrogen to yield methane (CH), or a complex process such as the oxidation of sugar in the human body, through a series of very complex electron transfer processes.
		Redox reactions are the foundation of electrochemical cells.
		The redox state is reflected in the balance of several sets of metabolites (e.g., lactate and pyruvate, beta-hydroxybutyrate and acetoacetate) whose interconversion is dependent on these ratios.

	redox (Site not responding. Last check: 2007-10-09)
		Redox potential is a an intensity parameter of overall redox reaction potential in the system (similar in concept to pH), not the capacity of the system for specific oxidation or reduction reactions.
		In the literature redox potential is generally reported as Eh, which is the potential generated between a platinum electrode and a standard hydrogen electrode when placed into the groundwater being tested, where hydrogen is considered the reference electrode.
		Redox reactions of light bioactive elements (C, H, O, and S) which most often involve the breaking of covalent bonds, a process that is normally slow.

		Redox potential is a value (number) defining how much gaining/losing a system might do; an oxidizing environment (one's we want) has a positive value.
		Redox is eminently important as an indicator not only of a system's capacity for cycling waste, but indeed of chemically supporting fish, plant, and invertebrate life.
		Redox is measured indirectly as the ability of an aquatic system to conduct electricity, in millivolts (mV, 1/1000 of a volt).

		In order to find the redox potential(s) of components in an uncharacterized system (for example, the cell membrane from a respiratory or photosynthetic bacterium which carries the electron transfer chain), the material is suspended in a stirred redox cuvette, which is placed in a spectrophotometer.
		The process is repeated over the redox range of interest, and a set of data obtained representing a redox titration of absorbance change as a function of ambient redox potential.
		Since the oxidized and reduced forms of the redox centers have different absorbance spectra, suitable choice of wavelength allows the absorbance change to be interpreted as a change in concentration of oxidized and reduced forms.

	Redox and Nitrogen Speciation in Subsurface Waters, US EPA
		While this observation of clustering for thermodynamically calculated potentials is suggestive of a redox control, the occurrence of two potentials, as opposed to a single potential expected for equilibrium, is suggestive of kinetic constraints as well.
		To evaluate which of these variables is the dominant in constraining redox reactions we reasoned that if the reactions are reactant-rate limited, deviation from equilibrium should be a function of reactant concentration.
		Using this approximation, organic nitrogen appears to be nearly in equilibrium with a cluster of oxidation potentials comprised of other nitrogen redox couples, oxygen-hydrogen peroxide and ferrous-ferric iron (Figure 4).

		Redox state is a widely used term for the description of redox phenomena in biological systems.
		But it was shown that changes in the redox state might lead to a cascade of intracellular events, beneficial or deleterious to the cell.
		As a result, changes in the intracellular redox state are not always accompanied by considerable changes of glutathione concentration.

	Hydrogen Peroxide - From Oxidative Stressor to Redox Regulator
		Changes in the redox environment could explain how T cells are informed early in the development of inflammation that they soon might or might not be needed.
		Thus, monitoring of redox related T cell events could become a diagnostic tool for early detection of inflammation at a time before damage is done.
		It seems that multiple steps in various T cell signal pathways are redox sensitive, so that the overall outcome of oxidative stimulation for the cells would be a weighted balance of the individual signaling activities.

		Redox potentials are absolutely simple to work with if you understand what they are about.
		Standard electrode potentials (redox potentials) are one way of measuring how easily a substance loses electrons.
		You have to be a little bit more careful this time, because the substance losing electrons is found on the right-hand side of one of these redox equilibria.

	Plant Sciences, Gideon Grafi,REDOX SIGNALS IN MOLECULAR ADAPTATION
		We established, in parallel, the redox state in organello of the regulatory VDS and redox effects on D1 synthesis in intact chloroplasts.
		However it is yet unclear how the VDS-containing proteins mediate signal transduction and regulation by redox, how redox signals are transmitted in an otherwise redox-buffered milieu (under nonstress conditions), and how regulation specificity is attained.
		Hence in the light, a counter-balanced action of reducing and oxidizing activities modulates the redox state of the pool of RB60, and consequently translation of psbA mRNA, in parallel with fluctuating light intensities.
