10-membered
Definition
- Adjective:
- Having a ring structure composed of ten atoms: Used specifically in chemistry to describe a molecule whose central or defining structural feature is a closed ring consisting of ten atoms. These atoms can be of the same or different elements.
Usage
- This term is a technical adjective used almost exclusively in scientific contexts, particularly in organic chemistry and pharmacology, to classify and describe cyclic compounds.
- It is typically placed before the noun it modifies (e.g., "a 10-membered ring").
- The hyphen is standard in this compound adjective when it precedes a noun.
Examples
- Adjective:
- The researcher synthesized a novel 10-membered lactone.
- This antibiotic's activity is due to its complex 10-membered ring system.
- Cyclodecane is a simple 10-membered hydrocarbon ring.
Advanced Usage
- The term is part of a systematic naming convention for ring sizes. Similar constructions are used for other ring sizes (e.g., 5-membered, 6-membered, 8-membered).
- It specifies the count of atoms in the ring but does not imply anything about the types of atoms (e.g., carbon, nitrogen, oxygen) or the presence of double bonds (unsaturation).
Variants and Related Words
- Decacyclic (adj): A less common synonym meaning consisting of a ten-atom ring.
- Ten-atom ring (noun phrase): The structure being described.
- Ring size (noun phrase): The general property that "10-membered" specifies.
Synonyms
- Decacyclic: Having a ten-membered ring structure.
Notes
- This is a highly specialized term. The number (10) is part of the adjective itself and changes to describe different ring sizes (e.g., 3-membered, 4-membered).
- It is not typically used in everyday language and has no idiomatic or phrasal verb applications.
Adjective
-
of a chemical compound having a ring with ten members
