| 설명 | 산화하는 작용 또는 산화된 상태. 화학적으로는 원자의 양전하의 증가 또는 음전하의 소실. 대부분의 생물학적 산화는 분자에서 1쌍의 수소원자의 제거(탈수소)로 이루어진다. 이 같은 산화는 수용체 분자의 환원을 동반해야 된다. 1가산화는 한 개의 전자의 소실을 가리키고, 2가산화는 두 개의 전자의 소실을 막는다. |

| 설명 | 자율신경계는 활동하고 있으나 수의운동이 전혀 불능한 상태를 말한다. 따라서 호흡, 심박은 지속하고 있으나 의식적인 활동을 일으키는 일은 할 수 없다. 원인은 두부외상-척추손상-뇌혈관손상-뇌척수종양-중독 등 여러 가지가 있지만, 가장 많은 것은 교통사고 등에 의한 머리외상이다. 대뇌의 표층부는 대뇌겉질이라 하는데, 이 곳에는 백 수 십억의 신경세포가 모여 있어서 운동-감각-의식 등의 작용을 담당하고 있다. 이 대뇌겉질의 손상을 입으면 운동기능이나 의식이 정지되고, 뇌줄기가 담당하는 호흡기능-소화기능-심장박동기능 밖에 하지 못하게 된다. |

| algal oxidation pond | <ecology> A wide, shallow pond used in waste water treatment, the algae produce oxygen so that bacteria can aerobically digest sewage in the water. (09 Oct 1997) |
|---|---|
| alpha-oxidation | A form of oxidation of fatty acids in which carbons are removed one at a time in the form of CO2; the alpha-carbon is first hydroxylated and then converted into a carbonyl; a deficiency of this pathway is associated with Refsum's disease. (05 Mar 2000) |
| auto-oxidation | The direct combination of a substance with molecular oxygen at ordinary temperatures. Synonym: autoxidation. (05 Mar 2000) |
| beta-oxidation | <biochemistry> The oxidative breakdown of fatty acids into acetyl-coenzyme A by repeated oxidation at the beta-carbon atom. Oxidation of the beta-carbon (carbon 3) of a fatty acid causes the formation of the beta-keto (beta-oxo) acid analog. This is of importance in fatty acid catabolism, the entire pathway for the catabolism of saturated fatty acids containing an even number of carbon atoms. Beta-oxidation is a part of this pathway and acetyl-CoA is a major product of this pathway. (05 Mar 2000) |
| beta-oxidation-condensation theory | <biochemistry> That the two carbon fragments split from the fatty acid molecule by beta-oxidation are converted to acetic acid and then condensed to acetoacetic acid. (05 Mar 2000) |
| biological oxidation | Decomposition of organic materials by microorganisms. (05 Dec 1998) |
| Meyerhof oxidation quotient | <biochemistry> An index for the effect of oxygen on glycolysis and on fermentation (i.e., on the Pasteur effect); equal to the rate of anaerobic fermentation minus the rate of aerobic respiration divided by the rate of oxygen uptake. (21 Jun 2000) |
| pyruvate oxidation factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| omega-oxidation | Oxidation at the carbon atom farthest removed (ω-carbon) from the carboxyl group (carbon 1); thus, in this pathway, a dicarboxylic acid is formed; an important pathway in the degradation of prostaglandins. (05 Mar 2000) |
| omega-oxidation theory | That the oxidation of fatty acids commences at the CH3 group, i.e., the terminal or omega-group; beta-oxidation then proceeds at both ends of the fatty acid chain. (05 Mar 2000) |
| oxidation | <biochemistry> The process whereby fatty acids are degraded in steps, losing 2 carbons as (acetyl) CoA. Involves CoA ester formation, desaturation, hydroxylation and oxidation before each cleavage. (18 Nov 1997) |
| oxidation-fermentation test | <investigation> A test to to determine whether a given bacterial strain has an oxidative or fermentativetype of metabolism by seeing what it doesto a carbohydrate substrate. (09 Oct 1997) |
| oxidation number | The number of electrons necessary to restore an atom in a combined state to its elemental form. (09 Oct 1997) |
| oxidation pond | A pond that contains partially treated wastewater which is then left to allow the growth of algae and bacteria which decompose therest of the waste. (09 Oct 1997) |
| oxidation-reduction | A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs. (12 Dec 1998) |
| oxidation state |
oxidation number: the degree of oxidation of an atom or ion or molecule; for simple atoms or ions the oxidation number is equal to the ionic charge; "the oxidation number of hydrogen is +1 and of oxygen is -2"

| oxidation state |
The oxidation state or oxidation number is defined as the sum of negative and positive charges in an atom, which indirectly indicates the number of electrons it has accepted or donated. The oxidation number is a convenient conceptual approximation when working with complex electrochemical reactions that eases the tracking of electrons and helps verify that they have been conserved. ...

| oxidation state |
the charge on an element if it is assumed that it is behaving as an ion, eg, in calcium chloride (CaCl 2 ), calcium has an oxidation state of +2 (Ca 2+ ) and chlorine has an oxidation state of -1 (Cl - ). As the definition suggests, this definition tends to breakdown in species with a high degree of covalent bonding.
