This is a reaction with oxygen, as in combustion. An oxidized molecule is generally one that has lost electrons. Reduction also takes palce during oxidation - if one substance is oxidised then anothr must be reduced.
Combining with oxygen. Burning is oxidation. A chemical reaction in which oxygen combines with another substance or in which hydrogen atoms or electrons are removed from a substance.
in a broad sense oxidation is the increase in positive valence of any element in a substance. On the basis of the electron theory, oxidation is a process in which an element losses electrons. In a narrow sense, oxidation means the chemical addition of oxygen to a substance.Found on http://www.hach.com/chemGlossary
An algebraic increase in the oxidation number; may correspond to a loss of electrons.Found on http://www.encyclo.co.uk/local/10003

(1) The complete, net removal of one or more electrons from a molecular entity (also called 'de-electronation'). (2) an increase in the oxidation number of any atom within any substrate (see HENDRICKSON, CRAM and HAMMOND (1970)). (3) Gain of oxygen and/or loss of hydrogen of an organic substrate. All oxidations meet criteria (1) and (2), and many m...Found on http://www.chem.qmul.ac.uk/iupac/gtpoc/NO.html
burning in oxygen, normally highly exothermic (heat releasing), but also any increase in oxidization sate, (i.e. loss of electrons). Results in the formation of an oxide, rusting or corroding.

oxidize; oxidizing; oxidized. Compare with reduction. Oxidation is the loss of one or more electrons by an atom, molecule, or ion. Oxidation is accompanied by an increase in oxidation number on the atoms, molecules, or ions that lose electrons. Found on http://antoine.frostburg.edu/chem/senese/101/glossary/o.shtml
The term oxidation originally meant a reaction in which oxygen combines chemically with another substance. More generally, oxidation is a part of a chemical reaction in which a reactant loses electrons (increase oxidation number). Simultaneous reduction of a different reactant must occur (redox reaction).Found on http://www.ktf-split.hr/periodni/en/abc/o.html

Swimming pool chemistry: The 'burning up' of organic waste and compounds in the pool water. It also refers to what you may see on your metal pool surfaces if your water is corrosive. Rust is a form of this kind of oxidation.

(1) A reaction in which there is an increase in valence resulting from a loss of electrons. Contrast with reduction. (2) A corrosion reaction in which the corroded metal forms an oxide; usually applied to reaction with a gas containing elemental oxygen, such as air.Found on http://www.encyclo.co.uk/local/20742
Originally, oxidation meant a chemical reaction in which oxygen combines with another substance. The usage of the word has been broadened to include any reaction in which electrons are transferred. The substance which gains electrons is the oxidising agent
