单词	rotamer
释义	rotamer /ˈrəʊtəmə / noun 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.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.... 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. If all rotamers clash with the rigid part of the protein, additional conformers are made by 300 rotations around the final bond. Origin 1960s: from rotational (see rotation) + -mer.
