oxidation

[ok′sidā′shən]

Etymology: Gk, oxys, sharp, genein, to produce, L, atio, process

1 any process in which the oxygen content in a compound or the number of bonds to oxygen (or another electronegative element, such as a halogen) is increased.

2 any reaction in which the positive valence of a compound or a radical is increased because of a loss of electrons.

3 any process in which the hydrogen content in a compound or the number of bonds to hydrogen (or another element of low electronegativity, such as a metal) is decreased. oxidize, v., oxidative, n.

oxidation [ok″sĭ-da´shun]

the act of oxidizing or state of being oxidized. Chemically it consists of the increase of positive charges on an atom or the loss of negative charges. Univalent oxidation indicates loss of one electron; divalent oxidation, the loss of two electrons. The opposite reaction to oxidation is reduction. adj., adj ox´idative.

oxidation (kˈ·s·dāˑ·shn),

n 1. a chemical reaction in which oxygen reacts with another atom, molecule, or compound to produce a new substance.
2. a comprehensive term used to describe the loss of at least one electron from a molecule, ion, or atom.

oxidation,

n the combination of oxygen with other elements to form oxides. The process in which an element gains electrons.

oxidation, beta,

n a metabolic process in which complex fatty acids are broken down into simple compounds.

oxidation, of metal,

n the formation of a surface oxide during the casting or soldering of a metal or during subsequent use by the patient.

alpha oxidation

important in the metabolism of fatty acids.

beta oxidation

major process for the oxidation of fatty acids in the body leading to the production of ATP. Occurs predominantly in the mitochondrial matrix, but can occur in peroxisomes. Oxidation of the fatty acid occurs at the beta-carbon, leading to the release of the preceding two carbon as acetyl CoA.

omega oxidation

oxidation beginning at the last carbon (omega carbon) of an acyl chain, usually a fatty acid.
