Oxidized
Oxidized
Oxidized (pronounced: /ˈɒksɪdaɪzd/) is a term used in various fields of medicine, particularly in biochemistry and pharmacology. It refers to the process or state in which a molecule, atom, or ion loses electrons, often involving the interaction with oxygen.
Etymology
The term "oxidized" is derived from the word "oxygen". It was first used in the late 18th century, when scientists discovered that substances could combine with oxygen in reactions that often led to the loss of electrons.
Related Terms
- Oxidation: The process by which a substance is oxidized.
- Reduction: The opposite of oxidation, where a molecule, atom, or ion gains electrons.
- Redox: A type of chemical reaction that involves both reduction and oxidation.
- Oxidative Stress: A state of imbalance between free radicals and antioxidants in the body, often leading to cellular damage.
- Antioxidant: A substance that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures.
In Medicine
In the field of medicine, the term "oxidized" is often used to describe the state of certain molecules in the body. For example, Oxidized LDL (Low-Density Lipoprotein) is a type of cholesterol that has been modified by oxidation, and is considered to be more harmful than normal LDL.
Oxidation reactions are also crucial in the metabolism of drugs and other substances in the body. The Liver is particularly involved in these processes, with enzymes such as the Cytochrome P450 family playing a key role.
