Oxidation

Meaning

In a biochemical context, oxidation is a fundamental chemical reaction involving the loss of electrons by a molecule, atom, or ion, which often results in an increase in the oxidation state. While essential for energy production through cellular respiration, uncontrolled or excessive oxidation generates reactive oxygen species (ROS), leading to cellular damage known as oxidative stress. Maintaining a delicate balance between oxidation and reduction is vital for cellular health and longevity.
