Oxidation

Oxidation is a chemical reaction that involves the moving of electrons from one substance to another. More specifically, it refers to the substance that gives away electrons. In the process of oxidation, the substance that gives away electrons is oxidized.

Oxidation is an essential part of many chemical reactions, especially in biochemistry. It is also a process that can cause damage to cells and tissues, leading to diseases such as cancer and heart disease.

History

The term "oxidation" was first used in the late 18th century by Antoine Lavoisier, who used it to describe the reaction of a substance with oxygen. However, the concept of oxidation has since been expanded to include any reaction in which electrons are transferred.

Oxidation in Biochemistry

In biochemistry, oxidation reactions are vital for the production of energy. The most notable example of this is the process of cellular respiration, in which glucose is oxidized to produce carbon dioxide and water, releasing energy in the process.

Oxidation in Industry

Oxidation reactions are also widely used in industry. For example, in the production of sulfuric acid, sulfur is oxidized to sulfur dioxide, which is then further oxidized to sulfur trioxide.

Oxidation and Disease

Oxidation reactions can also lead to the production of harmful substances known as free radicals. These can cause damage to cells and tissues, leading to diseases such as cancer and heart disease.
