Hydroxylation is a chemical reaction that is commonly found in biological systems. It involves the addition of a hydroxyl group (-OH) to a molecule. Some synonyms for hydroxylation include hydroxylating, hydroxylated, and hydroxylate. Another similar term is oxidation, which refers to a broader range of reactions that involve the addition of oxygen atoms to a molecule. Other related terms include alcohols, which are organic compounds that contain hydroxyl groups, and dehydration, which is the removal of a water molecule from a molecule, often as a result of hydroxylation. Overall, the study of hydroxylation is important in understanding many natural processes and can have implications for drug development and related fields.
