hydroxylate
C2 (Very low frequency, highly specialized)Technical/Scientific
Definition
Meaning
To introduce a hydroxyl group (-OH) into a compound.
The chemical process of adding a hydroxyl functional group to an organic molecule, often via enzymatic or synthetic reactions.
Linguistics
Semantic Notes
Used almost exclusively in chemistry, biochemistry, and pharmacology. The noun form 'hydroxylation' is more common than the verb.

Examples
By Part of Speech
verb
British English
- The enzyme will hydroxylate the steroid at the 11-beta position.
- We need to hydroxylate this aromatic ring to increase its solubility.
American English

- They hydroxylated the precursor compound before testing its activity.
adjective
British English
- The hydroxylated metabolite was detected by mass spectrometry.
- A fully hydroxylated surface was more hydrophilic.

Learning
Memory Aids
Mnemonic
HYDROXYLATE = HYDROXYL (the -OH group) + -ATE (verb suffix meaning 'to make'). Think: 'to make into a hydroxyl-containing compound'.
Conceptual Metaphor
CHEMICAL MODIFICATION IS INSERTION (a group is 'introduced' or 'added' to a molecule).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- False friend with 'гидроксилировать' – direct equivalent, but Russian may use the noun 'гидроксилирование' more frequently.
Common Mistakes
- Using 'hydrate' instead (adds water, not -OH).
- Confusing with 'hydrogenate' (adds hydrogen).
- Incorrect stress: /ˈhaɪdrɒksɪleɪt/ instead of /haɪˈdrɒksɪleɪt/.

FAQ
Frequently Asked Questions
No, it is a highly specialised technical term used almost exclusively in chemistry, biochemistry, and pharmacology.
'Hydrate' means to combine with or add water molecules. 'Hydroxylate' means to introduce a specific functional group (-OH) into an organic molecule's structure.
No, the verb form is 'hydroxylate'. The related noun is 'hydroxylation', which refers to the process or reaction.
Primarily in synthetic organic chemistry, drug metabolism studies (pharmacology), enzymology, and materials science when discussing surface modification.
