What does hydroxylate mean?
Hydroxylate is a technical verb meaning to introduce a hydroxyl group, written –OH, into a chemical compound. The process can add the group across an unsaturated bond or replace another functional group, and it often occurs in biochemical reactions mediated by enzymes. Hydroxylation is especially important in metabolism, because the liver and other tissues use it to alter drugs, hormones, and other biological molecules. The related noun hydroxylation names this transformation and is frequently used in descriptions of organic reactions and metabolic pathways. In general writing, the word is specialized and is better suited to scientific, medical, or industrial contexts than to everyday speech. Its meaning should not be confused with hydrolysis, which breaks chemical bonds using water rather than adding a hydroxyl group.
verbTo introduce a hydroxyl group (–OH) into a chemical compound, usually by replacing another functional group or adding to an unsaturated bond.
- To introduce a hydroxyl group (–OH) into a chemical compound.
"The enzyme hydroxylates the fatty acid during the first stage of metabolism."
"The reaction hydroxylates the aromatic ring and produces several closely related products."
"Cytochrome P450 enzymes hydroxylate many drugs in the liver."
Hydroxylation is the chemical shortcut for putting an –OH group on a molecule, a transformation central to both metabolism and modern industrial chemistry.

Etymology of hydroxylate
The word is formed from hydroxyl, a term for the –OH group, together with the suffix -ate, used here to indicate chemical modification or conversion. The related noun hydroxide also derives from this root and names a compound or ion containing –OH. Together, these words reflect the central importance of oxygen and hydrogen in organic chemistry.

How hydroxylate is actually used
This is primarily technical vocabulary in organic chemistry, biochemistry, and pharmacology. The related noun hydroxylation is more common when referring to the reaction or biological process as a whole.
Easily confused with hydroxylate
Hydroxylation adds a hydroxyl group to a compound, whereas hydrolysis breaks a chemical bond by reaction with water.
Hydroxylate is the process of introducing a hydroxyl group, while hydroxide is a compound or ion containing the hydroxide group, –OH.
