enzyme-catalyzed oxidation

Enzyme-catalyzed oxidation involves enzymes, specifically oxidoreductases, facilitating the removal of hydrogen atoms and electrons from compounds. These enzymes, often called dehydrogenases or oxidases, work with coenzymes that accept the hydrogen and electrons. In animals, these are eventually transferred to oxygen.1

Oxidation itself is a chemical process where an atom, ion, or molecule loses electrons. This electron transfer changes the substance's composition and energy state, playing a crucial role in various reactions, including metabolism, combustion, and corrosion. Enzymes like catalase are vital in biological systems, accelerating the breakdown of hydrogen peroxide into water and oxygen, thus preventing cellular damage. This process is fundamental to cellular respiration, where organic compounds are oxidized to carbon dioxide and water, often with the help of enzymatic catalysis.234
