A hydroxylation is a chemical process in which a hydroxyl group (OH) is added to a molecule. This type of reaction is common in organic chemistry and biochemistry. In many biological systems, hydroxylation is catalyzed by enzymes called hydroxylases. These enzymes play crucial roles in a wide variety of metabolic pathways, including the synthesis of hormones, the detoxification of drugs, and the breakdown of fatty acids.

Hydroxylation reactions can occur at different positions within a molecule, and the resulting hydroxylated compound may have significantly different properties from the original molecule. For example, the hydroxylation of cholesterol in the body leads to the production of vitamin D, which is essential for calcium absorption and bone health. In contrast, hydroxylation can also be a step in the metabolic activation of some toxins, making them more reactive and potentially harmful.

The introduction of a hydroxyl group can alter a molecule's polarity, solubility, and reactivity. This change can affect how a molecule interacts with other molecules, its ability to cross cell membranes, and its overall biological activity. Hydroxylation is a fundamental transformation that chemists and biologists utilize to modify and understand the function of organic compounds.
