释义

Definition of rotamer in English:

rotamer

noun ˈrəʊtəməˈrōdəmər
Chemistry
  • Any of a number of isomers of a molecule which can be interconverted by rotation of part of the molecule about a particular bond.

    〔化〕旋转异构体

    Example sentencesExamples
    • The effects of the membrane are clearly illustrated by the increased frequencies of hydrogen-bonding rotamers and the snorkeling of Trp and Tyr out of the membrane.
    • It is consistent with emission from different rotamers of the cyanine dyes formed immediately after excitation (vide supra).
    • If all rotamers clash with the rigid part of the protein, additional conformers are made by 300 rotations around the final bond.
    • Using broader Ï-values may result in broader distributions of rotamers, so we have avoided interpreting rotamer distributions that may be influenced in this manner.
    • In this study we use the dead-end elimination method to determine the possible rotamers of tryptophan.

Origin

1960s: from rotational (see rotation) + -mer.
