Hydroxylation is a chemical process that introduces a hydroxyl group (OH) into a molecule. This reaction is fundamental in organic chemistry and plays a crucial role in many biological systems. Hydroxyl groups are highly reactive and can alter the properties of a molecule, making it more soluble in water or more susceptible to further chemical reactions.

In industrial chemistry, hydroxylation is used to synthesize a variety of compounds. For example, phenol, an important industrial chemical, is produced by the hydroxylation of benzene. This process often involves the use of catalysts to facilitate the reaction and improve yield. Various oxidizing agents can be employed, with oxygen itself or hydrogen peroxide being common choices.

Biologically, hydroxylation is essential for many metabolic pathways. Enzymes called hydroxylases catalyze these reactions. For instance, in the human body, cytochrome P450 enzymes are a large family of hydroxylases responsible for metabolizing a wide range of endogenous and exogenous compounds, including drugs, toxins, and steroids. These enzymatic hydroxylations are critical for detoxification, hormone synthesis, and nutrient processing. They can occur at specific positions on a molecule, demonstrating remarkable selectivity. The introduction of a hydroxyl group can change a molecule's polarity, affecting its interaction with other molecules and its fate within a biological system.
