conformational, a. Chem.|kɒnfɔːˈmeɪʃənəl|
[f. conformation + -al.]
Of or pertaining to molecular conformation; conformational analysis, analysis of the reactions, energy, and other properties of a molecule in terms of its conformations.
1954Chem. Rev. LIV. 348 The modern theory of ‘conformational analysis’. 1968A. White et al. Princ. Biochem. (ed. 4) iv. 78 The conformational formula of cholestanol shows that the molecule is rigid. 1974Encycl. Brit. Macropædia IV. 1090/2 Conformational analysis is used..: (1) to correlate directly the properties of molecules with their preferred conformations and (2) to analyze the interplay of conformational preference with the geometrical requirements of the transition state in organic reactions. 1978Nature 14 Sept. 160/2 Taking into account the conformational flexibility about the phosphodiester bonds and the possible variations in the remaining torsion angles, the conformational features of regular helical polynucleotide were analysed. 1980Amer. Jrnl. Trop. Med. & Hygiene XXIX. 1028/2 Early studies..showed that VSGs consist of single polypeptides having similar molecular weights..but strikingly different amino acid compositions... Conservation of some conformational features was indicated by the results of experiments with trypsin.
Hence conforˈmationally adv., as regards conformation, in terms of conformation.
1958Jrnl. Amer. Chem. Soc. LXXX. 6103/1 The compound with the single signal has three conformationally equivalent hydrogens and must be in the conformation shown. 1974Tetrahedron Lett. XVII. 1573 The 12-membered ring containing sulfurs as in X is, in general, conformationally free from variable-temperature NMR analysis. 1978Nature 23 Feb. 708/3 The conformationally changed protein. |
