Definition of oxidation :
The loss of electrons.
Lipid alkoxyl radicals are presumed to be the species responsible for metal-amplified lipid peroxidation because of the chemical analogy of simple organic alkoxyl radicals to the hydroxyl radical.
Oxidation describes the loss of electrons by a molecule, atom or ion
Reduction describes the gain of electrons by a molecule, atom or ion ...
oxidation The loss of electrons from the outer shell of an atom; often accompanied by the transfer of a proton and thus involves the loss of a hydrogen ion. The loss of electrons or hydrogens in a chemical reaction. PICTURE ...
oxidation
The loss of electrons from a substance involved in a redox reaction.
oxidative phosphorylation ...
Oxidation and Reduction Reactions
Oxidation is the loss of electrons or hydrogen atoms. Oxidation reactions release energy.
Reduction is gain of electrons or hydrogen atoms and is associated with a gain of energy.
oxidation
A chemical process in which either electrons are lost from an atom, or oxygen is added to a molecule. Oxidation may also occur without the addition of oxygen if hydrogen is removed (dehydrogenation.) ...
Oxidation
Primary alcohols generally give aldehydes or carboxylic acids upon oxidation, while secondary alcohols give ketones. Tertiary alcohols resist oxidation.
Oxidation-reduction reaction A reaction that transfers electrons.
Oxidative phosphorylation The process in which ATP is formed as a result of the transfer of electrons from NADH or FADH2 to O2 by a series of electron carriers.
Oxidations and reductions always go together. They are called redox reactions.
Oxidation/reduction via an intermediary (energy carrier) compound, in this case NAD+. Images from Purves et al.
oxidation - removal of electrons
oxidative phosphorylation - the last step in catabolism and the point at which the major portion of metabolic energy is released.
oxidation The loss of an electron by an atom or molecule; sometimes addition of oxygen chemically to a substance. Opposite of reduction, in which an electron is accepted by an atom or molecule.
B oxidation of water, reduction of NADP+ , formation of ATP
C oxidation of water, recuction of NADP+ , hydrolysis of ATP
D fixation of carbon dioxide, release of oxygen, synthesis of glucose ...
carbohydrates, from carbon dioxide using energy obtained from light rather than the oxidation of chemical compounds."

The most-studied gene products in this organism are those involved in the oxidation of ammonia, principally the hydroxylamine oxidoreductase (HAO), ammonia monooxygenase (AMO), ...
The mitochondria contains the enzymes that carry out the Krebs Cycle, the metabolic pathway involved in the oxidation of the food we eat. These enzymes are in the fluid part of the matrix.
cellular respiration, which is the process utilized by cells to obtain energy from the oxidation of organic compounds accompanied by the consumption of oxygen (when available) and the release of carbon dioxide ...
Firefly luciferase protein catalyzes luciferin oxidation and light is generated in the reaction. The luciferase protein is frequently used as a report gene for measuring promoter activity or transfection efficiency.

These bacteria extract energy from the oxidation of ferrous ions (Fe2+) to ferric ions (Fe3+). Pyrite is one of the most common forms of iron in nature, and is very common in bituminous coals and in many ore bodies.
Precursor of a dye that is converted into colour by, for example, oxidation.
Chemosynthesis: The process whereby chemical energy is used to make organic compounds from inorganic compounds. One example is the oxidation of ammonia to nitrite by nitrifying bacteria. Compare photosynthesis.
Some types of peroxisomes, such as those in liver cells, detoxify alcohol and other harmful compounds by transferring hydrogen from the poisons to molecules of oxygen (a process termed oxidation).
