methylated
Adjective: 1. Chemically treated with a methyl group: Describes a substance, typically an alcohol, into which one or more methyl groups (–CH₃) have been introduced through a chemical process. 2. Denatured alcohol: Commonly refers specifically to ethanol (drinking alcohol) that has been made poisonous and undrinkable by the addition of methanol and often a purple dye, primarily for use as a fuel or solvent.
- General Chemical Process:
- The chemist analyzed the methylated sample to confirm the reaction was successful.
- This is a methylated form of the compound, which alters its solubility.
- Specific Reference to Denatured Alcohol:
- We used methylated spirits to clean the paintbrushes.
- Methylated alcohol is commonly sold as a fuel for camping stoves.
- "methylated against" (technical): A phrase used in biochemistry to describe DNA where cytosine bases have been methylated, often to regulate gene expression.
- The promoter region of the gene was heavily methylated, silencing its activity.
- Methylate (verb): To introduce a methyl group into a compound.
- The enzyme can methylate specific DNA sequences.
- Methylation (noun): The chemical process or result of adding a methyl group.
- DNA methylation is an important epigenetic mechanism.
- Demethylated (adjective): Having had a methyl group removed.
- Denatured (specifically for alcohol, when the context is clear).
- Treated (in a general chemical context).
The primary meaning is the chemical one. However, in everyday, non-scientific English (especially in British English), the term is overwhelmingly used as a short form for "methylated spirits," referring to the denatured alcohol product. The context usually makes the intended meaning clear.
