Definition of dimer in English:

dimer

noun ˈdʌɪməˈdaɪmər

Chemistry

A molecule or molecular complex consisting of two identical molecules linked together.
〔化〕二聚物，二聚体
Example sentencesExamples
- One explanation is the metal ions bind inside the dimer between the monomers of a double-helix.
- Furthermore, there was no evidence of ethyl esters, dimers, alkanes or alkenes, which might be expected for an oxidative reaction.
- Molecular dimers are assumed to be not directly degraded.
- In this paper, we synthesized a covalent dimer of alamethicin that was N-terminally linked by a disulfide bond.
- The resulting dimer forms an ion channel in lipid membranes that is selective for monovalent cations only.

Derivatives

dimeric

adjective

Chemistry

The derived molecular weights were consistent with dimeric or trimeric peptide.
Example sentencesExamples
- There was a previous radiation study of ricin, a dimeric molecule linked by a single disulfide bridge.
- In all cases the monomeric lipid molecule is virtually absent, dimeric or trimeric species predominating in each case.
- Previous work has shown that these polymerised forms are unstable in acid conditions (such as gastric juice) and that only monomeric, dimeric and trimeric forms are passed to the intestine for absorption.
- The reactions were followed spectrophotometrically at 300 nm, where the dimeric products of phenol coupling absorb.

Origin

1930s: from di-¹ 'two', on the pattern of polymer.
